    2007 grand prix gt supercharged with 3.6 pulley, cai, autolite 104s, res delete with 31" glasspack installed.

    Problem is, at about 3-8 boost "half throttle" it seems to miss...,i don't have this problem when boost isn't being used or at wide open throttle. it will "miss" then drive normal. Zero idle problems, no extra gas consumption.

    What is this?? Video below is view of whats going on, listen close at six seconds.

    Well if your car is tuned to see 195* then leave that in until your new pcm is installed
