Thanks Shane!

Rosey's had more topend power past 7000, until we got to the point that increasing boost down low did not effect the boost past 6800+ at all. Once the boost stopped moving up at all past 6800, then adding boost down low started hurting the very high RPM power. I assume we are overspinning the turbo so much that the backpressure is getting higher at those rpms and starting to choke it or we are ruining the compressor efficiency.
