Range Rover Evoque SD4 2.2 tuned in Hemel Hempstead, Hertfordshire.

This vehicle used to struggle when pulling away from junctions, roundabouts etc. We tuned this to improve that and it certainly delivered!

Now running around 230BHP / 470NM. Gains of +40BHP / +50NM.

The importance of checking cars before tuning....

This VXR we went out to tune had some instantly noticeable symptoms. Whether related or not, it caused us to start investigating further.

Smoking from the exhaust and the engine felt lazy when revving. We started digging. On this VXR we found low compression on cylinders 3 and 4. Cylinders 1 and 2 were very close to our limit too. The engine was breathing heavy on idle too from the crank vent on the front of the rocker cover. There is something wrong with this engine and it’s not fit to be tuned.

On this VXR our list of things found wrong was:

- Low compression on cylinders 3 and 4 (Pic is cylinder 3).
- Heavy breathing from crank case vent.
- Faulty one way valve on rocker cover.
- Front tyres close to the limit.
- Rear tyres close to the limit and minor cracking around the edges.

Mileage doesn't play into this either, this VXR only had around 65K miles on it with full service history.

If you have any symptoms of your vehicle that you think something might not be right, get it checked. Regular routine checks are good to make sure everything is running well and doing as it should do. If you do then have any faults, they can be caught and fixed early (and before tuning is attempted).

Shame for the owner but always better to know beforehand as you say.

Looking forward to getting my car done Thursday.. I hope theres nothing wrong with it 😁

Wow , only 65k ! Make me worry abit mines on 108k now. Sure mine is pukka tho

Was still Pushing 160psi A little on the noisy side though πŸ˜‚ (Z16LET)

What would cause this low compression as mine is also 110 psi across all 4 cylinders

Compression kits are about £30 ish. Or pop to a local garage n offer them a box of beers the week before your cars due to be mapped 🀷‍♂️ another good idea is to spend a tenner on a tiny USB camera n stick it down into the sparkplug hole n look around for heavy score marks on the cylinder walls and for any obvious piston damage πŸ‘ buy once, use a hundred times πŸ˜‰

No excuse for a poorly maintained car. End of.

Vauxhall Vectra VXR tuned in Market Drayton, Shropshire.

This Vectra surprised us upon arrival. This had done over 205,000 MILES! We have never seen one with this high mileage, Let alone tuned one!

This car performed really well. It had Insignia VXR turbo and Injectors, front mount intercooler and a high flow exhaust system.

We firstly scaled the injectors to ensure they worked perfect and were correctly calibrated. Then we tuned it. During tuning we saw nearly 1000KG/H airflow. Based on our usual calculations this Vectra is now running around 340-345BHP. Certainly, good going for the mileage!

Volkswagen Golf R Tuned in Oxford.

This customer had used us before back in 2015 with a Vectra VXR they used to own. After selling that and getting this Golf R they wanted to see what we could do to it! The owner was very impressed with the tuning service we provided and we did exactly what they were looking for.

This Golf is now running around 350BHP / 450NM.

Kia Sorento 2.2 tuned in Reading.

Sometimes even with all our tuning tools we still have to open up ECU's for programming. This one today only needed 1 boot pin which made life a lot simpler!

This Kia is mainly used for towing caravans and needed some extra pulling power. We tuned this to stage 1 giving an extra 33BHP / 64NM. This takes peak power to around 230BHP / 500NM. This should pull caravans with ease now!

Vauxhall Zafira GSi tuned in Beverley, East Yorkshire.

We travelled over 200 miles each way to take our tuning services to the door of this customer. He had used us before on a previous vehicle a few years back and now wanted us to tune this.

The ECU was already tuned in this Zafira, but it was a flash map taken from the internet etc.. The list of things wrong with this map on this car was endless...

- Knock sensor deleted
- Both lambda sensors deleted
- Coolant temp sensor deleted
- scaled for a stock map sensor but running a 3 bar
- VXR injectors scaled wrong.
- Using the cruise control caused the car to accelerate at full speed instead of maintaining the current speed.

This is becoming more and more common these days, people flashing maps on vehicles with Β£10 tuning tools and Β£5 internet maps. It is dangerous and not good for your engine one bit. The owner of this car just knew something wasn't right with it.

The turbo was weak on this car, but we still managed to get the car setup correctly and back to running how it should be! It's now producing around 260BHP. With plans for more once the turbo has been fixed.
