I replaced everything except for ecu and coilpack all my mods are updated in profile. I have no idea what to do it only does this at idle.

Not sure what it is doing. Sounds like it has an idle surge is this correct if so check your vacuum lines and do a boost leek test

Correct me if i am wrong but i don't hear any misfire. Idles alittle high, let it worm up and see where it settles. boost leak test wouldn't hurt

Doesn't sound like a consistent missfire, if a missfire at all.

Yea no boost leak and all brand new vacuum line. Thanks for the input though it weird I did a bunch of pulls tonight only little misfires at idle almost sounds like my fuel pump causes it because its a 255 that's not rewired.

Anyone else have a problem like this

I'm not hearing anything out of the ordinary. If anything, check the ISC and your plugs.

How did you ensure no boost leaks?
