The "cut" so to speak, is between 6200 and 6400 RPM. This corresponds with the point at which the MAF flow #'s clip. Basically it hits like 266 G/Sec and stops. (I think it's 266, it's been too long since I looked at it, I need to start logging that stat now I guess)

Problem is, I don't know how that reading possibly affects anything when the MAF Volts continue to climb/index on the table.

I may need to send some data to a pro tuner and see what they think might be happening... if the lump at the end there extended from 6100RPM and then rolled off closer to redline, I think we would see much more impressive top end numbers. It seems aborted, the way it is right now.
