im only getting 38 psi line off. is it ok for our cars to go wide open throttle with that vacuum line off the regulator? i want to see what fuel psi i have at WOT with the line off. with the line on and 14 pounds of boost i hit 51 fuel psi at WOT. is this ok?

Not to be mean, but are you kidding??? Seriously, if you're really thinking about trying that you're asking for a blown headgasket.

The entire reason for a boost sensitive regulator is so the FP goes up with boost, if you don't use it you are asking for a MAJOR lean condition (that's when it's HG time)...FP should always be set line off because that's the only time that engine Vac/boost will not affect it.

oops. sorry i had a brain fart there. i dont know why i even asked tthat question.
anyways, does 38 line off 51 with 14 pounds of boost sound ok?

As long as you are not getting knock. There's other variables to take into account - weather, octane, intercooler efficiency, timing, etc - Just make sure you are Not knocking

Does injector size play in on what fuel preasure you'll want to run? I oredered some 60 high Z's and a chip and I will be retuning so what should my FP be? still 43 static?

Is 43 just the static for the 86-87s, or does it go for the 84-85s as well?
