8psi LS turbo, LEAN at 4,000 rpm and up!!! PLEASE HELP!
Hello there, I just finished my turbo setup, I am using an S-AFC, 450cc injectors and a T28 turbo boostin 8psi, with a pretty good sized spearco intercooler ofcourse.. anyways, Boost comes in at about 2,800rpm, and continues to build up till about 4 thousand full boost, The car is pulling hard from 2,800 to 4,000 and then the car bogs down and a/f gauge is LEAN LEAN! Do I need to raise the Fuel pressure or something?? is that why?? or what do you think is wrong?? I am using my stock fuel pressure regulator.. why is the car bogging down and the a/f gauge FULL LEAN!?? got my safc set to 35% accross the rpm range...
thanks,
Mark

I think he ment gauge ?
If you are going off a narrow band A/F gauge that uses you stock sensor or even one that come with a sensor like the greddy one than it is NOT going to help you TUNE your engine. You NEED a WIDEBAND
You also proly have a bad stock sensor

yeah, but a christmas-tree guage running lean is blow-motor lean.
I'd try richening up your AFC a bunch. 5-8% maybe? That's what it's there for you know... The AFC hack isn't about a flat percentage as much as a flat AFR
