I'm assuming peak was 7100 which says u moved that up ~ 200rpm. Is this stock cams?

 Nice work on you concept and testing the results. Does look like you may have extended the power under the curve at the upper RPM range. That's useful!

Re: Frankenplenum
Went back to look at the last time I tuned my setup specifically, what happened at 7100rpm. HP was pretty flat losing 4hp between peak of 6850 and 7100rpm.
That seems to suggest little contribution from added plenum volume BUT the tune needs to be cleaned up before drawing any conclusions.
