L1C,
Well, my mileage seems to be about 16+MPG. Though, I don't do that much fwy driving. 12 miles total between home and work 50/50 driving city/fwy. I do have to go between 2 offices that are about a mile apart. And yes I will push down the "go pedal" a little. I suspect if I did more fwy driving it would get better.
Would I buy the Jacobs product again? Hard to say. I bought it from Jacobs for $450. Had it installed for $200. It does not make the difference the Superchip did.But it does enhance the overall performance of the truck.
I do have the K&N FIPK kit and Flowmaster muffler installed, so it doesn't seem that as a single piece the Jacobs offers much. But who knows if the difference would be more noticeable if my truck was stock?
