Volkswagen Scirocco 2.0 TDI 181 bhp

I've had nearly three weeks now to assess my Sciroccos' performance since it was remapped and I wanted to say a big thanks to the whole team at Celtic Derby for completely transforming the car and with no detriment whatsoever to fuel economy. It's been money well spent and I would highly recommend a stage one remap to anyone with the same model.Thanks again guys.

Celtic Tuning have been remapping my cars for over 10 years and never once had a single issue, can't recommend enough! They got my brand new VW Golf GTI MK8 to 320bhp and feels as refined as if it came out of the factory with that much power, the DSG works perfect and has made me love my GTI all over again, keep it up!!

Volkswagen CC 2.0 TDI 174 bhp Diesel

After purchasing the CC Black R-Line edition. Could not wait for this to be done, went for the 174bhp as better gains than the 181bhp. And the power is awesome just what the car needed. Run a couple of test times 0 50km 3.2s 0 80km 5.6s not bad, big respect to the boys at Celtic for keeping the price down number one for me.

Thank you CT team for rectifying my van.For sorting out the remap done elsewhere, and saving me a large amount of money so that I don’t have to replace my clutch, caused by the previous remap. Not only did you fix the problem but you gave me a better, more usable map with more power. To me, that’s worth the small cost all day long! Thank you
