spooned out

when i was boosting my unreliable autometer A/F gauge didn't show me signs of running lean at all!!!! and i don't have an EGT or VAFC yet, i just installed a new 255 walbro pump and it idles much better then before, i still have stock FPR and currently have the Greddy "blue box" for FCU, could my blue box be the thing thats making me run lean???? and how can i check myself to see if im running lean without going back to the dyno with my same setup?

if anything, your blue box will make you run rich. invest in a WBO2 such as the TechEdge and you'll know for sure

WB02? TechEdge? give me more info or a site i can go too

those air/fuel guages work believe it or not.....well to an extent. Hook the wires up wrong and it will stay rich all the time. Make sure your wiring is correct.

I would check the plugs first. If it turns all white then you know.

check your plugs, do a search there is a lot of info about this
