Yeah for automatic to shift close to factory, dialed in for tires makes speedometer 3 mph fast...I knocked tires down half inch to get mph correct but shifts hard, fast, or however one wants to call it in first 2 gears. I have 4.10 gears but pulling 18 inch rims. Plenty of power, just quick to hit revs and throws in higher gear Lil to soon. There is no rim size on superchip. I don't know if that is problem with 18 instead of 17 inch that came with factory, but doubt it. I called superchip but give up after 10 min hold. May try again.
