Question hypertech?

Wonderin if anyone has done all the guess and checks? Just bought a hypertech tuner for my 2001 silverado with 5.3L. Wonderin if anyone knows what I should set the rev limiter and the transmision shift point MPH & RPM to? any suggestions I could try would be good. It's hard to find the setting with the most power and performance.

They are not the best, but come in handy for some changes. You dont want to raise the rev limiter too much, maybe 300rpm, Same thing for your shiftpoints, maybe 1-2 mph
