Re: Tunner?
If You do not go with tuner after what you have done you will not get all out of the other upgrades that they can bring to the table. You increased ability for air flow in and out but, nothing to add more fuel and timing to get the real power You have set yourself up to have.

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?
