i mentioned launch controll when Boostedhfrex talked to me about it, so we just set it to enguage outside of the rev line, 8900 or something, so its basically disabled, i had that issue with my car so i thought of it as well.

so yea it is turbo, and the plugs are gapped at .030

i also thought that it could be the turbo blowing out the spark, but when we pulled the spark plugs and they had a good gap..

AFRs should spike lean whenever the engine is breaking up.

dont think that its going to fix it...

Its not like the plugs are gapped to .04 or bigger, that is a decent gap for a turbo plug... but still something to try when all else fails...

and sry to restate wht BHFR said, he posted while i was typin
