Great engine and gearbox tune but need to be aware of some points

Audi A7 3.0 TDI 268 bhp Diesel

I have the 3.0 tdi 272hp engine, which has been transformed by the remap. The power is now linear and the throttle response in ‘drive’ is more predictable. In sport mode, the car goes like a scalded cat! The 7-speed dsg remap has allowed the additional torque to be handled generally well but you do need to be aware that the box will be more harsh on low speed changes.
I haven’t noticed any difference in fuel economy so it does seem that there is extra power at no noticeable efficiency cost.

Wow. Where do I start?What a difference this has made to my vehicle, the low down power and the way it powers through the revs.The only regret I have is that I didn't do it sooner.Big thanks to KEVIN the technician, what a gent!And the guys at CELTIC TUNING.5 stars.

Highly recommended, the improvement on my Audi A6 S-Line Ultra is amazing, really pleased with remap and very noticeable gains, more than I expected, yet better fuel economy. Friendly staff and service was top quality.

Thanks to the team 👍

Just had my Q5 tuned last week. It is like a new car. Much smoother and masses more pull from low revs.

Nice engineer took about 40 mins to upload it and tell me about the guarantee and how I could have it taken back to standard for free within 14 days. No chance. Best thing I have done to a car.

Early days yet but the computer is telling me we are getting more mpg too. Can't fault it.

Well done Celtic.
