Default Re: Tunner?

Well i purchased a hypertech power programmer III for my rig. With what i have installed as far as intake and exhaust any suggestions on settings for best performance? according to what i have read in other post (unless someone tells me different) setup will be as follows:

2004 Hummer H2
87 Octane
128 MPH
6100 Rev Limiter
Increase shift firmness

Gear Shifts
1-2......+3
2-3......+5
3-4......+7

Does this look good or has someone found a better tweek?
