I just remembered I don't have the injector clips hooked up to them. I guess that will be the 1st thing I do tomorrow.

Check the electrical pins in the injectors. When I sent mine to FIC to be flow matched to ensure they were good. They told me one pin in one injector was folded down. I am confident I was on 7 injectors for quite some time because when I got them back and installed them, the BLMs changed big time compared to before I pulled them. BTW the injectors were dead nuts equal.

K will double check the pins during the install. I'm sure they're fine though. I wish I had a garage I'd get it done tonight.

PROBLEM SOLVED!!!
Turned out to be a leaking injector. I pop'd the hood and saw a small puddle of fuel sitting on the intake.

YEP! Its always the tune. Your tune blew up my first LT1. I sent it to you for a NA LT4 hotcam tune with full bolt ons etc. Then decided to spray the **** out of it with the same tune, no retard, and stock plugs and fuel pump.
See its always the tune. LMAO!

Just hooked up a fuel pressure tester to my car here are the results.

has 45psi car off primed.
has 40psi car on but when I open the throttle it comes down to like 35-37psi.
I unhook the vacuum off the FPR and it jumps up to 48psi and stays there even when I open the throttle.

Just wanted to ask before I spent the money. FPR?
