At wide open throttle, under 6500 rpm the MAP pressure seems good at around -0.4 to -0.9, but every time as soon as it reaches 6500 rpm the pressure decreases to about -1.5 to -2. Does this mean anything, in terms of efficiency, or maybe the tune isn't as good as it can be?
I have a 3.75in CAI, stock TB and Manifold, and 3.75in Invidia Exhaust. My first thought was maybe the Cam Angles were not optimized. Is there a rough estimate of what they should be with that setup at high rpm.

I mean 2.75in exhaust.

That is pretty common from what I have experienced with the 9th gens. 8th gens seems to run columns 9-10 and the 9th gens run in 8-9 in WOT. Nothing to worry about.
