when my engine is cold and i drive it in vacum at around 2000RPM before my turbo hits it jerks badly like i'm giving it gas and lettting it go and giving it gas aand letting it go constantly...this is very ------- annoying does anyone know why its like that? its ony doing this after my turbo setup, could it be too rich? Only when its cold though.

 

let your car warm up before you take it out.

 

Are you boosting when its cold? you better let that ---- warmup to normal temp before boosting. Also are you running uber?Maybe you need a better tune.

 

running TE, and i did boost when it was cold a few times cause the bogging just pissed me right off so i ripped it. But yeah i know its not good so i try to not do that again. But when i say cold i don't mean anything like winter conditions, just a cool unwarmed car. Its weird cause i could drive my car like that in N/A with a cold engine no problem.

 

something is up with your fuel or ignition map. double check your dizzy timing too.

 

Its your tune man, and you don't boost untill its warmed up because pistions and ---- expand and its not good for the rings and such.
