I had my GTI 1.8T remapped there (Stage 1)and also my ED30 done there too, had stage 2 custom map (Intake and Full TBE) remap done and got 316bhp and 342lb/ft.
The owners son had a LOT of work done on his previous ED30 there (Around 400bhp with hybrid turbo), I would gladly recommend them.
Niki at R-Tech did my DSG remap and I would also be very happy to take any car to him, top bloke!
