Running lean, any advice?
I know my fuel management isn't the greatest but I never thought it was this bad. I just had a baseline dyno done on my Turbo LS running about 10lbs of boost. I have an intank fuel pump and a vortech 12:1 running off of stock injectors. At about 3 1/2 thousand rpms the Air to Fuel Ratio jumps all the way to 15 and stays pretty constant, we stopped the run at about 5,000 rpms. I wanted to hear of some temporary solutions just to get it running a little richer. I have some RC 310s coming. I can't afford standalone since I have an OBDII motor. Do you think 310s and safc may help in making it run rich. Should I keep the vortech 12:1 FMU when I add the bigger injectors, or is that too much pressure in the fuel lines when I get the 310s. Any advice would be great

Re: Running lean, any advice? (wzcb08)
run the hack, (440's vafc) vortech 12:1 sux. I cant believe it made it that lean. Mine was so rich that it stopped pulling above 5600. But i bet 310's with the 12:1 and a vafc would work too, i would rather go with the hack though. But also i dont know if 10 psi is to much for that set up??? mine was at 7 when it was richer than hell, 10 might be leaning it di you try less boost at the tuners???

Nope, the spring's lowest boost on the wastegate is 10, but i just bought a 7psi spring and will get that in there too.

Here's a link to my A/F Graph so you can see what I was talking about. You think it's possible my FMU is not working right anymore. I have about 10,000 miles, is there any maintence that needs to be done to a vortech fmu. Let me know if the link works or not too.
