Reviews

What customers say

The gearbox is so much more responsive since having the Stage 3 tune! Gearchanges are a lot faster, the car accelerates much quicker. By far my favourite bit is the full manual, with the paddle conversion its just so much better to drive!
Ollie BMW 335D Diesel
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
Took my car in for a DSG service as they were able to get me booked in within short notice. Staff are very helpful and very happy with the overall experience. Would recommend!
