At the end of the graph power is dropping slightly, which is what we see on just about all engines of course.
Is boost still at 22psi up there and if so, is power falling off due to timing, fueling, volumetric efficiency?
Could this be tuned around slightly by running 3.5 bar sensors and taking boost above 22psi, or is that turbo upgrade time? If so, do you have any experience yet with Pure stage 2?
