I too would recommend an aftermarket tune. The Procharger tune usually isnt stellar. I recommend Lund or PBD.
Otherwise, false knock can be a real issue. First thing to check is the AC line going near the intake tube to the throttle body. Make sure it's bent far enough out of the way or wrap it with something so its not metal/metal contact if it touches the pipe when the motor torques. I would check there first if you say the exhaust is stock.
Your MAF should be reading much higher but it could be something off in the tune. It's not possible to install it incorrectly in the intercooler. What pulley are you running and have you checked with a boost gauge other than the boost box (which have been known to have accuracy problems in the past)
