So, . . . . the big question. What WERE you looking for? That's HUGE (if it's true) but you're not impressed? Hummmmmmmmmmmmmmm.

I think the OP was more interested in the improved shifting points that 5 Star Tune provides. If anyone buys a 5 Star Tune for improved gas mileage, they haven't read the reviews available on line. Some do report a little improvement, but the majority of praise is for the improved shifting performance and perhaps a little better acceleration when needed.
And, I'm a happy 5 Star Tuner user!
