this mk3 GTI a friend and i built out in Washington has one of the first Kinetic VRT kits(stage 2 intercooled version) on it. we went to the dyno with the old C2 obd2 chip, stock cams, stock compression, stock cat back exhaust
271whp @ 11.5 psi on Kinetics dyno.
so at 9psi with the 268s, and an exhaust i see 280-290 being very possible.
one question though, it says TT eprom for the Cams, then you also say the C2 30# software… which is it
