fuel pressure

[chiken]

my fuel pressure is set at 48 lbs with the vacume line off. i was wondering approx. how many pounds it goes to at wide open throttle. any ideas?

how many pounds of boost??????? just take 48 plus # pounds of boost, and you have what the fuel pressure SHOULD be at WOT.

And 48 psi seems awfully high for a base FP. I'm used to seeing 38-43 normally.

Errr, uh, that's too much fuel for an Armstrong chip. Read the instructions that came with it - if you have them that is. I think he calls for 42 to 44 psi line off. Readjust your pressure and then reset the ecm.

Yeah thats up there. My R/A chip calls for 43

I'll be the fourth to say that's about 5 psi too high. It's officially a pile on.
