i thought id do a bit of debrief.. well first thing the car is much nicer to drive! heaps more boost downlow and gets on boost much faster.. very happy with it so far.. done 200kms no error yet for not having the factory unit plugged in.. only thing i dont like is that it seems have trouble running anything over 12psi.. occasionally it will run 14 though it seems to have trouble holding it even lower in the rev range.. does this mean i need a scotty special wastegate spring?
