Could also be the manufacturing variances in pipe size. Perhaps the MAF is reading a big better because the pipe sent to him originally was out of spec?
Either way, I'm completely stock now (ecu wise) and still have the same issue you, yourself experienced 2 nights ago. I've triple checked my install, everything is tight.
