I just put on a new pt44. Know under boost it starts to break up and falls on its face. It does hesitate a little when taking off. Any ideas i tried tapping on the maf but it didnt do anything. Any other ideas
Did you remember to hook the ground strap back up that mounts between the turbo mounting bracket and the block? If not it could be messing with the electrical systems on the car and causing your problems. Also is your coil pack O.K.? Maybe coil pack went out at the same time you replaced turbo as a coincidence.
