if i was to start again the fuel pump would be my first mod as it's the part which constricts the performance of the car the most
both apr and revo offer a stage 1+ (hpfp) map which wiill give you the most noticeable performsnce gains over stock.
back on superchips i had their stage 3 map put on - (tbe,cai & hpfp req) in february the difference between stage 2 (tbe & cai req) and 3 was hardly noticeable
once the giac dsg map was on i further realised the limits of the bluefin map as steve p mentioned they don't know how to remove the soft limiter on the car so when you rev the dsg box beyond the 6200rpm limit, the power just drops off and lags before you can change gear
the change to revo 2+ was incredible, remember driving home after the remap, had the biggest smile on my face, in all conditions the car was so just so much more responsive
