is there a certain size screw you are suppose to use? if so what size?
what did you guys use? and what is it suppose to do exactly?

Alot of people said after 6k rpms it drops back down, well mine doesnt, if that a bad sign?

 

It wont drop down with the 06 Cobalts and mines a 05 and it doesnt drop back down so i dont know if one of the recalls eliminated this problem. Anyone else shed some light on the conversation

 

It gained nothing on my 06 when it was at the dyno. I'm not sure about 05's.

 

so no boost bypass is needed? because once it hit 15's psi and i powershift it stays at 15.
