just out of curiousty, to compare with my setup, what fp are you guys running w/ larger injectors?

right now, mine are 315 and about 62psi @ 8lbs of boost

seems low to me, what are your guys numbers like?

um yes that is low, when i was runnin 315's i was running 100 psi at 9 psi boost, if you use the fuel injector flow rate calculations and a .80 duty cycle you should be near the proper flow rates, but running at 65 psi is pretty dang low!

If you are using a S-AFC,you can assume a DC of 0.80 or whatever. If you aren't using a S-AFC, you must assume a DC of 1. The stock ECU will run the injectors near 100% if you don't trick into doing otherwise (S-AFC). The assumed DC will make a big difference in the fuel pressure that you aim for. I just wanted to state that, in case either of you didn't take that into account.

Gimme fuel...Gimme fire...Gimme that which I desire

damn dude, 100psi??? i ran 100psi on stock injectors, thats way too high

i dont have a safc, so im basing duty cycle at nearly 100%

also, my a/f still shows 1.0v and egts are 1500-1520 upto 90 or so on a WOT run

no one else has run bigger injectors? im just trying to compare what everyone else is running to what im doing. my pressure seems low, but egts are fine and a/f says im way too rich (1.0v :O )

used your page corbin, the example helped a lot. figured i need ~70psi of fp w/ 315cc injectors @ 9psi of boost, figuring a 100% duty cycle since i have no SAFC
