Better low-midrange response w/o supercharging?

If you change the gearing go ahead and go 4:88. I have 4:88 gearing and a 5star 93 octain performance tune, still on 35's and its neck snapping quick. I dont care about the gas milage.

You're not going to get any real scientific data on this. MPGs in these trucks is always dependent on usage and driving style. You may do slightly better around town with a light foot. But if you've got a heavy foot and you cruise at 90 on the freeway, you're going to lose something.

Try the tune first.

I'm not looking to improve MPG. I just want better power delivery/responsiveness . I only mentioned the gas mileage because I'm sure gears would kill it.

Who sells tuners and can program it?
