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.

 

Good deal.

 

Damn tunes?

Amazing how many problems end this way...I had a guy complain to me how I always blamed his car, someone touch his TB and it literally fell off the car.

 

Glad to see you found the problem!

haha, yeah man. the other day i was cleaning out my TB and i realized two of the four bolts holding it to the intake had completely backed out. fixed that one real quick

 

Thx, I wonder what my car will dyno now

 

Good luck at least it should be correct now--and changes will yeild predictable readings

 

Yep, it's ALWAYS than damn computer!!

You can alwasy tell which is the dumbest person in a group when something like this comes up. It's always the first one to chirp "It's the tune!"

 

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!

 

 

Epic 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?
