poping when trying to accel

[hosser37]

alright, i have 2g gsx, with a ebay turbo t3t4 installed, that i just dropped in this summer and has been ran less than 100 miles sense then(project car)... before it started snowing the car was running great, finally it started getting cold about 2 months ago. 2 months ago it had a real bad hesitation pretty much untill boost. after it went through a coolant cycle or two the hesitation slowly faded. now its reaching 0 deg. and today i went out to move the car for the plow guy and, now, as soon as i push on the gas it starts to pop and/or backfire quite rapidly. a guy that was helping me with the project took out honey combs from the mas to lean it out. told me lean is fast.. could this cold of weather be causing the car to run to lean and thus cause poping/backfiring like that? also, i dont know if this could help diagnose the problem, but my alt. went and is being rebuilt right now so im running straight from the battery... thanks a lot ,
Bill

quick question that might help a lot. is your stock boost gauge working?

no its routed straight from the housing to the wastegate. im just using the springs they gave me for the wastegate, im running the weakest spring they gave me... i think its 5psi or something low.

Sounds like you could have a bad vacuum leak causing to much air to get in and causing a dangerous lean mixture if it is as bad as you say it is.

i checked it out today, im still waiting for my alt. but i did find that the hood and the nipple on the bov (to intake)kinda wore a hole in it, ill find out tomorrow if that helps it.. if it doesnt work should i try increasing my boost to something higher than 5psi?
