lol same,
Im currently sitting at 286 bhp on a wrx after being remapped and wondering whats the max ill get out my turbo through a remap?

Tidgy

judging by your other post yur switching to a vf35 turbo, you'll need to uprate the injectors and you'll need to uprate the fuel pump and then get it remapped.

The version 8 WRX has 380cc injectors, my 03 was making 332bhp/311llb/ft but the injectors were maxing at 106% duty cycle. They should run at no more than 80-85%. I fitted used STI pinks 550cc and the cycle issue is resolved and the car is making 340bhp 314lbs/ft. It's had quite a bit done to it by the way.

106%? So does that mean they were supplying more fuel than they should?
