Cummins QSC 8.3 flash?

[Stephen4785]

A little more background. The owner of this machine bought it brand new. From day one he didn't like the power out put. He's owned several of these mulchers and other brands with the same engines and he said that the other ones don't bog down near as much. Same QSC but different hp ratings. He's requesting that I reflash it with a higher hp rating. I told him I would check on it. If it's possible I would flash it, he would test it, and then pull the data to see what the pressure/temps were doing. As long as everything looked good then keep it but if not I would load the original calibration back on.
