What customers say

Arrived 8.30 Saturday morning, a technician armed with laptop tuned the gearbox,so now the truck changes earlier keeping the revs lower,I was a bit hesitate about having it done,but it's definitely better with no problems.
Mark Grindell Toyota
I got a stage 1 tune for a Golf R, engine and gearbox. This is our family car so it was about tightening up the response and adding low-end torque to improve driveability. I turned up, the job was done while I waited (less than an hour). They had free coffee and good wifi so…
Richard Henderson VW
A great experience from initial requirement through to completing the work. Gave good explanations as to what the XHP tune would do and how it would improve gearbox performance of the M3.
