alright guys, i have a misfire under boost. i can push the throttle anywhere up to 5lbs of boost. anything after that, and it starts misfiring intermittently and randomly, sometimes bad enough to throw it into limp mode and it drops it down to 5lbs of boost again. i can let off and hit it again, and it will do the exact same thing, any gear, anywhere in the boost that can go above 5lbs. 8-10lbs and it starts freaking out. could it be a loss of fuel pressure? bad pump? bad maf? clogged filter? has anyone else had this issue? the plugs look lean, it was just number three, now they are all getting lean, and the problem is getting worse and worse. any thoughts guys? i know you are all some geniuses and have the answer. haha.

I had a similar problem once it was a bad coil pack replaced them and it stopped. just a thought.
