Yes same thing happens on the stock ECU, but now they are thinking it could possibly be the sensors and/or throttle body since it's only getting 50% throttle at WOT. And trust, the original person is not re-tuning the car. I'm getting a log of the stock tune this weekend, and then taking it to the dealer and telling them it's been really jerky and not boosting because I wont be able to tell if the tune is good if there is a mechanical problem that's not fixed. So I'll probably have a legit answer in a couple weeks, until then I'm babying the shit out of this thing .
