Actually zero is within the specified range for both toe-in and camber, so that is not all that radical a setting.

The idea of more speeds is to eventually get the engine RPM at a given road speed to a minimum without a big jolt in engine speeds.

Low engine speed at a given riad speed has long been effective for improving MPG because it minimizes engine frictional HP. This loss is protional to engine speed below 2000 RPM in the T444 and slightly hyperbolic above.

This mod is pricey, but in my view this truck is now a form of hot-rod and not just some weak "duct tape and coroplast" dabbling.

If I don't mess up my air dam, I expect 30 MPG. There is no EPA mileage for this truck but most guys report 14-16 MPG, so I'll have the average effectively doubled.
