I just got this 86 GN and need to know what to put my fuel pressure at.It is all stock with stock exhaust and catalytic conv still intact with stock downpipe also.It was at 50 psi with line off but that is high compared to the non IC car I had.The boost is spiking to 15 then drops down to 12,it pulls good but falls off on the top end like the timing is being pulled out.The motor has only 33k original miles.I have a adj wastegate,K&N,and adj fuel pressure regulator.Everything else including chip is stock and untouched.
I am going to mod it with the usual stuff over the winter but need someone to recommend what fuel pressure and boost level I should run for now or anything else I should know.The primary fuel is Sunoco 94.TIA
