well it wont hurt. I do know the v401 MAPs are more aggressive than the v300 MAPs. You may also be getting throttle closures due to "over boost" which I can't tell until we get some better logs. If so its an easy fix with ATR, as reported with other users...

FYI, I hit ~19 psi mid range with my stock turbo's. PTF Pro Tune FTW!
