Superchip Heavy Tow Option
I recently purchased the Superchip 1714, I agree it certainly does "wake up" my '04 screw, without much gas mileage penalty. There are a couple of screens that ask whether or not I am towing over 4000 lbs. I normally select no as I don't tow often. I don't see any observable changes in performance when selecting a yes answer to these heavy tow option screens. Can anyone tell me what a yes answer to these screens does in terms of changes in the program? I would assume it would alter the shape of the torque curve, bringing it on a bit more at lower RPM, but can't tell from the on road performance.
