Obtained a remap and to say as always such a wonderful experience as perusal. The power delivery and output is tremendous Amg 35 and bmw 330d plus 530d have all test. But have failed thanks to these guys and this supersonic remap. Thanks Celtic bloodclart.

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 👍
