My calibrator thinks the dyno load brake is causing the dip in the line. He thinks it is the nature of this dyno.Is there a known reason for that torque dip from 2700-3400 rpms? I wonder if the deletion of the 3rd cat will smooth that out. Also, why doesn't the dyno run continue all the way to redline instead of stopping at 6400-6500 rpms? Is this just a difference in the dyno reading and the car?
