2011 Vagon with upper pulley upgrade, ported throttle body and CIA. It has a 91 octane pully tune / firm shit from Diablo in-tune handheld. Ive noticed a delay in the shift from 2-3 gear, even hitting the rev limiter at WOT. A few days later the car began making grinding a noise (I assume is the transmission) when started and at slow speeds and the check engine light came on. It showed P0700. Is this a tune issue or do I have a serious problems. The car only has 17K miles. Thanks for any input
