Now I was looking at this dyno chart and it seems that with just the MREV2 the TQ and HP values cross the baseline and dip below it from 6200 or so RPM to the revlimiter. They were able to make the lines intersect at a higher point when using it in combination with the 5/16" iso thermal spacer. With the MREV2 in combination with the 5/16" spacer there was also a cross over to the power and tq loss sides after 6400RPM or so all the way up to redline.

Has anyone been able to figure out a way to make this cross a little higher up in the RPM range?

With this power drop being noticed would it be more reasonable then to be shifting at the range where power begins to drop significantly (dHP/dt and dtorque/dt) ???
