Some guys have noticed gains at high rpm's when increasing fuel pressure slightly. Me I'm at 33 psi.

the real way to see if it would like to have some more pressure is to look at the blms at various rpms and try to balance them out as much as possible by varying the pressure. You also want the O2 to be around .88 volts at WOT.
