Guys i have just fitted a DTUK FSR tuning box and am more than happy with it....the power seems to kick in just before 4000rpm and that gives you plenty of grunt when you are looking for it...below is the figures from DTUK web site
Make / Model GOLF VII 2.0 TSI 230PS GTI (Performance Pack)
Standard KW (PS) 169 (230 PS)
Tuned KW (PS) 205 (280 PS)
Standard Torque 350 Nm Tuned Torque 410 Nm
So happy bunny with these figures..
