stumble off idle & backfire when...

[newtowner]

I get a stumble off idle if I don't ease into it. Nail it on the highway , an as it builds boost it will back fire through exhaust. If I build boost to 3-5 psi from a dead start it runs like a raped ape. Static pressure is at 41# and boost at about 18. Setup is stock motor, te44, 009's, 3" DP, cat and exhaust, ATR cold air, and Armstrong 93 chip. The lap top I have took a dump so I can't scan it. I will get another laptop tommorow, just thought I would get some input before I try to solve these problems.

Check your cam sensor setting.

ill put my money on your EGR valve

easy test...disco the vaccum line from it. then plug the vaccum hose with something and see if you have any more problems if not your EGR vaccum controller is bad like mine.

If that doesnt work hows your grounds?

how is it running now??

Its the 009s. Check your instructions with Red's 93 chip. I think he says 43 to 44 psi of fuel. (double check me there though!!) Tempermental injectors IMO. I can't wait to ditch mine. Any takers???
