See sig for set up. I *just* installed 80# injectors and TT chip hoping that was my problem; too small injectors...negative. And the problem is - I've got awesome power in 1st gear at 20 psi boost, but around the top of 2nd gear and by the time it's in 3rd, it's falling flat on the power, only building to about 15-17# boost, and then often completely dying. It still feels it's not getting enough fuel.
I don't have a power logger, but now that I've put in the 80#ers, I'd think I could at least troubleshoot this problem w/o one (on a budget). I've jacked up with fuel pressure to 54 psi with line off, and that's not helping. It was 41 when I first got the FP gauge, then read some are setting to 50 and Nick Micale recommended 50 as well, so I set it there, then up to 54.
The last Scanmaster O2 reading (if I don't stay in it until it fully dies), was 828 (after upping the fuel at the chip 10.2%). I had another runs in the high 700's prior to adding fuel on the chip. So I'm confused.
The motor was built by Nick Micale, and I think the new fuel filter he put in is a stock style. Fuel lines are all stock to my knowledge. Volts on the Scanmaster are reading typically 13.6-13.9 at the start of the run, and may drop to low 13's or high 12's by the time it's falling flat. But the pump is hot wired, so the SM isn't picking up the volts going to the pump, right? Is it safe to assume the fuel pump is getting ample voltage?
So...I've got a freshly built motor with tons o' power and potentially lots more with more boost...but can't think about that until I resolve this problem. If I go through the gears at 75% throttle, and keep it at 15 psi, it's fine through 3rd gear, and continues to pull.
