Question about MAP pressure
Posted: Sun Oct 20, 2019 11:40 am
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 Catless 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.
