My Mercedes C320 had a Swirl Flaps issue, bottom end was dead. My mechanic did the Swirl flaps removal, Celtic Tuning did the rest. From my initial helpful telephone conversation, right through to me dropping the car, friendly staff, nice waiting room and the result of a stage 1 ECU remap and indicator fault light being removed is superb. The car goes like an absolute dream, thank you.

Fantastic service from start to finish. I have not had a car remapped before and have put in a lot of research and decided on Celtic Tuning from the fantastic reviews across all platforms. I was sceptical about the gains claimed and also whether it would actually be noticeable at the wheel and not just on a print off from the Dyno... I was wrong. My Audi Q3 2.0tdi went from 148bhp 275lbs/ft to 196bhp 350lbs/ft and it's a different vehicle. Especially the motorway pull 50-70+mph is incredibly different. the best way to describe it is, it feels like you are in one lower gear so 3rd feels like 2nd, 4th feels like 3rd etc. and when driving economically there is a 2-3mpg increase too as a bonus. My only reservation is whether reliability will be affected I have been assured it is not but time will tell. If reliability is not affected I will be getting all future cars remapped by Celtic Tuning.
