Should not be as Travis and Rodney basically are running a bunch more boost and the shortblock was not messed with (according to Travis) for a couple of years.
There may be other things going on with the engine calibration that we are not aware of.
Believe Rodney and Travis used the FAST XFI system for several years and then recently Travis had training on the Holley System.
Not sure if Justin is using the Holley System or the FAST stuff. Justin does all of the calibration stuff himself and is a sharp tuner.
