someone should put up a stock rev-up dyno so Bryan can post up the best shift points for that also. IMO the best 1-2 shift point is at 6600-6800 rpm

because if you go all the way to 7200 the tires wont chirp second gear.

I need to add tire sizing, so I can figure how many "mph" that you will spend outside of the optimized powerband by shifting at alternative engine speeds. You can then way the time spent outside the powerband, verse the time with traction loss. The traction loss is also not necessarily a total loss. My gut feel is stay in the powerband, but I'll dig up some more data to come through.
