I noticed this the same as Travis. Sam how come the SC run ends at roughly 7300RPM where the stock one is roughly 7600RPM?

Most probably because he did not want to run it into the rev limiter on boost and let off earlier. Since revs climbed significantly faster then without boost he probably cound't "time" it better.

330 isn't 340-350, but who cares, lol. Very good dyno numbers from GTM.

All he did was fine tune this...lets imagine for once, whats going to happen with 2 more psi + full exhaust. I agree tho, very nice numbers so far. Especially for Stage 1...
