Noooooo! Not what I wanted to hear derf! May be time for a billet wheel and tial wastgates from EPP. Hopefully they have a core in Stock. I leave town for about a month at the end of the month and don't want to leave her at home sick 
Derf, by the way did you ever run a FORSCAN or any other device to possibly isolate the problem?
I never ran anything with forscan, just used my X4 to check for codes, and livelink to try and get logs. my issue was present with the stock tune and my AJP tune as well. In my case, I went to the track, after having some revisions done to the tune, and a few extra mods, hoping for a low 12's or magical 11's pass. previous best was a 12.87. So I expected atleast that. Ran a 12.9 on my first pass, and after that I could not get out of the high 13's/Low 14's(stock like performance). I noticed the boost gauge didnt seem to be at my commanded boost during one pass (commanded was between 15 and 16psi and it looked to be ~5PSI). Sent Brad the logs and went from there. I was kind of looking for an excuse to do upgraded turbos so the conclusion of either a turbo issue or wastegates didnt bother me too much, as it would have been a good excuse. I did notice my CAI was a bit loose during troubleshooting but that was really it. After a fresh cal download I could nail it and get to my peak boost command for a split second, at which point boost dropped off and it went into a more underboost like condition. I did talk to a local tuner/shop and they offered to diagnose but sadly I had to part ways with the SHO before that. It should be noted that in my case, I believe one of the turbos got damaged somehow, and the other was trying to work overtime to hit my commanded boost. My next step was going to be returning to stock entirely, and taking it in to a dealership to try and get it fixed under warranty, and if it turned out to be turbos/wastegates then upgrade after. Note that my car had less than 16k on it at the time.
