ok thought I might add my results... only just picked the car up yesterday
2860 - 9s from GCG
Stock motor... only mods are the turbos, cat back exhaust and PFC
270rwkw @ 15 psi... not a bad result I thought
standard AFMs were maxing out + injectors are almost at their limits
tuner said the shitty complaince cat is also holding back 15-20kw
now the goal is to get all the supporting mods, wind up the boost and go for 350rwkw
