Positive: Professionalism, Punctuality, QualityDecided to have my Mazda 3mps re-mapped to get that extra bit of power. After much research, decided to go with Xtreme tuning. Had a text conversation with Kathryn, (I chose not to phone) She answered all my queries and questions, so I booked an appointment at home. Chris and Kathryn turned up on time, and Chris explained everything in detail about the whole process. After around an hour the work was completed, and Chris told me to take my car for a test ride. Now bearing in mind the car was already 256bhp, the tuning produced 305bhp and 100n/m more torque. The result is absolutely amazing. My mps is now a seriously quick car, acceleration in any gear has improved tremendously, mid range torque is ferousious with no turbo lag. The remap has transformed my 12 year old car into a beast, with tremendous (dry clear road) overtaking abilities. I would recommend Xtreme to anyone. It is a safe remap, designed to get the best out of your car, without fear of engine damage. Chris and Kathryn were very professional, very knowledgable, and very passionate about their product and service, above all, exceptionally nice people. 100% great product and service. I am a person who is hard to please, but would recommend Xtreme to anyone considering a re-map on any vehicle.

I had my Audi A5 Sportsback 2011 re-mapped by Xtreme tuning. I had the car for 4yrs now and it felt like it needed a boost. Made a few calls and was recommended to use Xtreme tuning.
I called out Xtreme tuning.The guys came out and did their thing. Very professional.
My car now feels like a brand new car with the power I needed. Very quick and no lags at all. Just goes… Also I noticed the car is more efficient. More miles to the gallon. Nice one!

Refreshing to find a company with pure passion and love for what they do along with nothing but honesty and integrity.

I took my e46 325i cabby to them for a remap along a carbon clean service.

They were thorough, professional and very honest. They reported to me that the car had already been remapped rather than taking my money without me knowing any better!

The carbon clean has made an affective change to the performance of the car, from idling to actually driving.

Very very happy and a customer who will be returning for sure. Highly recommended!

Cheers!
