@Skizzo Did you see much difference with the cutout open/closed.
Is your cutout before or after the rear Cat. Thanks Justin

@Iarado there was no significant difference between open and closed. The two runs you see I the graph..one is open and one is closed. The truck made 1wtq more with it closed which basically means nothing.
My cut out is before where the stock cat would be. It is about a foot after the header
