Do any of the for mentioned programmers make the mileage worst than it already is? I am getting almost 14/16 mpg in my 07 and am pretty thankful for that. :D

Is yours bone stock? 14/16 is awesome!

Im begining to think that is pretty awesome too, its only two mpg less than what my silverado was getting. I read a thread on hypermiling, so thats what ive been doing.Its not alot of fun driving like an old lady but the mileage really shows a difference when you do. I was late getting somewhere today so drove it pretty hard and ended up with a 13.2mpg . Still not too bad compared to some of the postings Ive seen on here.

OK, here is a question that maybe someone will have an answer for... I have 4.88's for the gears and I have a superchips Cortex which does run up to 4.88 on the gear size. Only problem I am having now is I went up to 40's on the tire size a week or so ago and my cortex only goes up to 38's. Looked into Hypertech and they go up to 44's on tires, but don't support 4.88 gears. Anyone know of a chip that would work for my situation?

Cortex is making it work for now, but I am pretty sure my speedo is off...
