Sean, a fantastic bloke who will go out of his way. His professional, thorough and explained whilst tuning my car. Sean worked his magic and I’m so happy with the performance and economical on my Merc. CLC. When Sean said to go for a test drive. First thing came out of my mouth was “holy crap” when I applied the accelerator. I would highly recommend Sean and was really great pleasure to meet him. Thank you so much Sean.

Sean came to my home to remap my Zafira VXR today. I’d been in contact with him for a few months, to make sure I got everything I needed on the car to get the best possible result. He gave me all the help I needed and was always happy to give me advice. Finally, I got my Zaf ready to be mapped and Sean was really happy for me. Booked it in super quick and on a date that suited me. When he turned up, he was super friendly and really thought highly of my Zaf. He didn’t need to tweek anything and remapped it with so much knowledge and confidence, I trusted him immediately. I was super impressed and above all my result was SO good! I am well happy! Will definitely be back if I add anything on. Can’t recommend SM tuning enough - 10/10 for service and knowledge. Thanks again Sean

After having bought a non runner and forging the engine, fitting a new turbo and various other new parts and basically running out of ideas I contacted sm tuning to look at my map and carry out some diagnostics/data logging. Sean came down and basically confirmed my suspicions as to the map already on the car causing a few issues and after some investigation turns out the ecu was from a zafira and the map was possibly not even for this particular car in the first place. The car now drives smooth off boost and pulls like a train when the turbo kicks in, it was nice to speak to someone who knows what they're doing and doesn't mind giving decent advice even when asking stupid questions. Would definitely recommend and will be back for more tuning in the near future when carrying out more modifications. One very happy customer!

Sean's customer service is second to none, very friendly, explained the remap procedure in detail before he worked on the car. After the remap the car felt like it had been fitted with an extra turbo !! Now pulls much harder than before, Sean also says I should get better fuel economy as well, what's not to like ! More power and better fuel economy, thanks Sean your a top bloke.

Sean came out and remapped my Astra about a month ago. Prior to coming out, I emailed him and he was very helpful. My car is pretty high mileage and there was a bunch of stuff wrong with it but Sean was a great help. The car was remapped to over 160BHP and it's not just an increase in power, the car feels completely different, it feels a lot smoother! The fuel consumption seems to have gone up slightly too, it gives me over 60mpg on my 70 mile commute into central London which is great. All in all, top work and Sean is a very knowledgeable and good guy. Would definitely recommend.

Had Sean remap my zafira today and wow, what a difference. Previous map was appalling and very unusable.

BMW 535d & Vauxhall insignia cdti

★★★★★
5 5 1
Had Sean out today to map two cars for me. firstly the Vauxhall insignia 2.0 cdti now running 205 bhp, car is now pulling very hard whilst been extremely smooth is a joy to drive! Such a big difference over the standard tune. Secondly my 535d, Sean picked apart the poor map that was on the vehicle from a previous tuner, now running issue free for the first time in a very long while and is also a joy to drive. A complete new file was written and loaded taking into consideration the existing modifications on the car. Running 360-370bhp with huge torque it's now an externally quick car. Cannot fault Sean one bit, the time it took was no issue, the care taken and the passion shown were second to none!!! Would recommend to anybody, and without doubt be using again. Only gives me an option to leave 5 stars but if 10 were available Sean would be definitely getting 10/10 Would also like to add about the communication prior to the mapping. Sean is an extremely busy man but always took the time to get back to me, I had messages from him at 11pm and 5am! Nothing was to much trouble.

Definitely going to be my first port of call when it comes to my gsi needing some tweeks before hitting the road. Thanks again Sean

I asked Sean to remap my Vxr using the sport button,also to improve fuel economy in standard form (sport button off). I wanted the car to drive more smoothly with a more progressive feel. I must say he has achieved all of the above,the car is standard apart from a free flow panel air filter and the stage 1 remap. What a difference it has made to the drivability of the car. In standard form (sport button off) it is smooth and easy to drive,great for a daily commute. But with the sport button on it goes like stink, putting a huge grin on my face. Thank you Sean for your efficient service, a guy who obviously enjoys what he does, and is damn good at it too.

This was my first full remap from Sean and to say im happy is an understatement! Sean was very professional and really knows his stuff, willing to answer and explain any query you have. Lets you test drive the vehicle first to see if your happy before he even thinks about payment. The map itself is very smooth when you want it to be but also aggressive if you wanna have some fun, really puts you back in the seat. Even better on fuel now too. Cant wait to get more parts fitted and go back for a tweak. Wont hesitate to use him again and highly recommend his work

Sean travelled close on 300 miles with a gamble that my car couldn't be tuned because I had the later B20NFT engine but never the less he took to the challenge and his travel distance and time had paid off. Upon arrival he already knew I had the new ecu software and proceeded to try and remap my car. After 15 minutes of genie magic on his computer we were ready to roll down the road!. What a difference the car pulls like a train in every gear! I can honestly say doesn't matter what tuner I use I am sceptic of whether I'm getting a custom map or somebody else's map put on my car and Sean assured me everything is as it should be with my car and it's spot on which put my mind at ease. Can highly recommend anybody to get Sean to remap their car was a pleasure letting you work on my car buddy. Thanks again and smile per gallon even though I'm only doing 1000 miles a year lol

Perfect job done by SM Tuning on my Corsa C, I can't fault it in the slightest from start to finish. I was a little worried about getting the corsa mapped as I've seen what 'can go wrong' but Sean was quick to put my mind at ease and extremely professional. During the map there were a couple of hiccups - the alternator belt snapping being one of them! I thought it was all over but Sean was determined to complete the map and managed to do this with a battery pack he had with him. 405bhp later and I'm a very, VERY happy customer! His knowledge and experience really does speak volumes and shows just how passionate Sean is about what he does; plus nothing was too much trouble. I would recommend SM Tuning to anyone, I can guarantee you won't be disappointed. Thank you SM Tuning!

Throughout my build Sean offered me sound and knowledgeable advise whether it be fueling or otherwise. He directed me to people I did not know existed for parts I couldn't of asked for more. It was finally finished and he organised me a rolling road map session with the team at flow dynamics. We fell into at few problems with boost issues and an incorrect boost solenoid connection all diagnosed by Sean. After back to back runs Sean ironed the car out to perform perfectly and more importantly safely for the road and I left with the biggest grin on my face. For me. There is no other option. The guy is 100 percent in the work he does and I would never go anywhere else. Your in safe hands.

I have had my car mapped by SMtuning on both Road and a dyno. Both times the mapping was extremely good and after the final map it was clear that incredible performance gains were added to my vehicle with plenty of safety still remaining, We even did some testing on a then pre-production intercooler made by Airtec and sent them the results. But that's not what impressed me the most. I was totally blown away by the extraordinary customer service offered. Every little detail was explained to me during the mapping stage so I learned alot as to how it was done and why, my car showed several issues which had been discovered by sean prior to the remapping. But instead of sending me away to repair the vehicle myself SMtuning aided me in choosing and sourcing replacement items at great value. He also assisted me with fitting larger injectors in preparation of the final remap. The work Sean does is fantastic but the other worldly satisfaction given by the extra knowledge, explanations and help sourcing parts is what has made me recommend him to all my friends and has fixed my mind to have me return to SMtuning for every remap and tweak I have on ALL future cars.

I have been using sean and sm tuning for a number of years now and he is the only tuner i allow to work on my car due to the service he provides and excellent results every time My car was road mapped by sean a fair few months ago with no issues he taylored it to my requests and was ready to answer any questions i asked as he always does I recently visited sean at flo dynamics and the rolling road they have to have my current mapped tweaked for a larger intercooler it was strapped to the rollers and i thought it was gonna be a tweak but sean decided the map needed updating and started from fresh. This is the level of service that makes sean and sm tuning stand above the rest in my opinion and 1 of the reasons i only ever use and recommend him. Every question i asked he was more than helpful with answers and the results speak for themselves after he had finished it made 293.7 bhp and 347lb of torque it was then taken off the rollers and given to me to drive and what can i say the map is so smooth and just pulls to the redline if you want to push it that hard i returned paid my money after getting another couple of stickers to further advertise his company I have to add that on a few occasions i have messaged sean with questions and he has always replied in good time and offered invalueable advise Some may say i'm bias as i've only ever used sm tuning but when your tuner offers such an excellent service and the results that exceed your expectations why go any where else So keep up the good work sean and sm tuning

Sean came to me today to map my Gsi. A top man very professional and got straight to work. After a few runs the car started to pull like a train apart from a slight miss fire which Sean advised fitting different plugs which he supplied off his van. With the misfire gone and a few more runs including dropping the hard cut limiter to 6500rpm sounds nice! The car is nearly 100%sorted Sean advised to uprate the inter cooler as intake temps were alittle high and possibly a better actuator to control the boost better. I would recommend Sean to anyone he's not just a turn up map and go he makes sure everything is to his standard and gives you advice to make your car perform as it should. I will definitely use sm tuning in the future.

Sean remapped both cars. The gsi had an unknown stage 2 map and I asked Sean to put it back to standard with a tweak to compliment the pre cat decat. I was amazed with the result. Real good feel to it. Smooth through the boost range and purs on idle. The vxr Sean said the air intake temps were to high and safely mapped it to its potential. He advised me to get a better intercooler and come back and get it done again which I will. Vxr is very 'torquey' and 22 psi on boost. Top quality service and would recommend Sean to anyone.

Sean booked me in around 6 weeks from his first available date and was definitely worth the wait! Turned up on time and let me know an expected time of arrival and was very professional from first contact. He wrote a map for my S3 first and has absolutely transformed the car, we went on a road test while he checked all the logs and ensured it ran as it was meant to. Pulls harder than ever before and definitely worth the money! Brings a smile to my face! Then, he began to map my fabia vrs, it seems he's freed up so much power, the cars much more happy to accelerate through the rev range rather than just for the standard 1500 usable revs. What a difference! Highly recommended due to the advice, service and price were spot on! will be using in the future when i get a new car!

I recommend his work to anyone, it's top quality and I would definately use again in future. Thanks Josh

Sean came all the way to South Wales to custom remap my car. Firstly really nice guy, really helpful and cannot fault his attention to detail. I'm very happy with the car it pulls really well through the gears and the map has made the car deliver the power so much better. Approx 272bhp stage 2, I'm happy with that

Great service provided by a top bloke. Sean is very respectful of your car treating as if it was his own and on top of that he was an ace bloke to sit and have a chat to the whole time he was there. The map is fantastic we went through a few hours of testing to get it just right and the boost is smooth and pulls like a train right through the rev range with out droping off, meaning its real usable power. Would highly recommend to anyone wanting real world performance gains.

Heard about Sean at SM Tuning from a couple of mates. From the day of contact, he dealt with my inquiry & booking very professionally. On the day, he started by explaining about what he was going to do & we took the car for a spin. He continued to adjust the map after each run with explaining what he was doing. I've had maps done by your generic mappers before but after this experience with SM Tuning, it will remind me not to go anywhere else for my vehicle mapping! I couldn't recommend him enough! The car drives completely different & everything compliments the modifications. Excellent service, cracking map & top customer service.

A brilliant service from SMTuning from start to finish. Not only did he do a great job mapping but also a 700 mile round trip to come to me and do it and at a very reasonable price. Car is alot better to drive compared to a map from another tuner that was on previously and pulls right to the redline with the added extra of an ignition cut rev limit. Would recommend sean to anyone who wants the most out of their car but also to know that it is done safely as he will not leave until he is happy.

I had been having issues with the car blowing airflow meters so I got in contact with Sean in the hope he could resolve the issues. Not only did he sort out the running issues with the car but he also performed a custom remap totally transforming the car. The difference is amazing. All this was done in front of me, Sean was happy to explain each step he took during the whole process. I would 100% recommend Sean to anyone who is looking for a custom remap! a genuine and very friendly guy. Just need an exhaust and VXR injectors now!! Thanks again mate

After having the car mapped by Sean approx 18 months ago, I\'d changed the FMIC and inlet manifold so it was in need of of \'tweak\'. Sean not only took the time to alter the map numerous times to get it right, we also went on about 5 relatively long distance runs to test it each time and when a boost hose popped off, he did a boost leak test and gave me a free Mikalor clamp to hold the hose on! Really happy with the results. The car feels much more responsive now and pulls really hard right the way to the red line. Definitely recommend. Cheers. \r\n\r\nDave - Astra Cabby Turbo.

Spent hours doing reasearch on whos best to map my car.. honestly get booked in. Sean came to me and mapped my vxr, not only did he explain everything he was doing although most of it went over my head he is a perfectionist. Fueling had to be spot on. Boost levels had to be stable and i wanted a nice progressive drive but all the power i could hope for when i need it... thats just what he did. \\r\\n\\r\\nLook no further and dont settle for a generic map. This is a real custom map. \\r\\n\\r\\nHey, you even get economy out of it too as i done scotland on a tank!!! \\r\\n\\r\\nHappy days \\r\\n\\r\\nLuigi malena\\r\\nNorthamptonshire

Had my map done by Sean, it\'s amazing. I previously had a generic Stage 1 flash on their and the tyres I had used to struggle for grip with that. Sean the absolute genius made my car quicker yet smoother. With the new found power, i actually get more grip just for the sheer fact how smooth it is. The pops and bangs are great too, the ignition cut limiter is on another level. A nice party piece haha. \r\n\r\nMods I had consisted off, \r\nVxr turbo \r\nVxr maf \r\nVxr injectors \r\nFmic \r\nXev inlet cam \r\nHigh flow inlet manifold\r\n3inch downpipe\r\n\r\nSean guessed around 285/290 bhp, i actually rolled 302bhp 3 times in a row. It just shows how good his mapping is too, consistently hitting that 3 times. \r\n\r\nI would recommend Sean to anyone everytime.
