“SM Tuning applied a map to my Mazda 3.  Sean arrived at the agreed time, performed a car health check prior to mapping, following the mapping we did a test drive to ensure everything was working correctly.  Very good service.”


David Hendry

“Wouldn’t go to anyone else, Sean is so knowledgeable and can answer any question thrown at him giving you the confidence that your car is in safe hands. He came out to me to a time that suited me. I have used SM Tuning twice now both for BMW cars & will use him again for my next car too!!”


Matthew Chandler

“I had my A1 black edition mapped by Sean. It was my first time having a vehicle remapped, Sean was super helpful with any queries, very friendly and well impressed with the difference in power. Highly recommend.”


Charlie Parry

“I have used Sean twice now, first for a stage 2 map on my Astra VXR and more recently a stage 1 ECU and DSG map on my MK7.5 Golf GTI Performance. Both times Sean went above and beyond to answer any of my questions and was more than happy to give an in depth explanation of the work he was carrying out. He carried out a health check on both vehicles first and performed logging after the maps were complete and made any necessary slight changes to ensure both cars were running correctly and safely. He also keeps in contact afterwards just to check there are no issues and I know he would be willing to help if there ever was. I would highly recommend Sean to anyone looking for a remap."


Nathan Ames

“I’ve dealt with Sean at SM tuning multiple times and every time has been a pleasure from start to finish and always achieves good safe results With all aspects explained through the process and the knowledge this guy has is never ending.


I had a transit connect tuned with dpf and egr delete and kept going into limp mode with the generic map so Sean made a custom map and he wouldn’t leave until it was perfect and I was happy.
Brilliant tuner I would recommend to anyone.”


Jamie Girt

“What a great service Sean gave. He mapped 3 vehicle's for me on the same day, Land Rover Defender Skoda Superb with engine and DSG remap and a Skoda Fabia. All had noticeable gains. Very happy and would certainly recommend for anyone who wants to do the same. I had to apologize for all the messages and questions I asked but he was always happy to help I wanted to know I was going with the right company and I can 100% say I made the right choice. Give him a call or drop a message Sean will 100% sort you out...”
