Is there a way to make the tranny shift a little sooner so that we get better mileage? Is there a tool out there and who makes it?

 

Sure thing Vince.
It's called a Superchips 1715. You can get one online easily. You can adjust shift points and revs, speed limiter and all that good stuff. Just search it out.

oh, and always switch to a K & N air filter.
