First off... I love my Predator!!! and I love the forum and support. It has been awesome to be able to come on here and get answers and support. Great job guys.

I do a lot of around town stop and go driving, stop lights, parking lots, ect. I was wondering if there is something that I can adjust to see better gas mileage during this type of driving.

Oh, it's a 2007 Denali XL with 6.2 and 6 speed transmission.
Thanks in advance.

Stop and go traffic is the worst. There is not much on your end or ours for that matter that will help in this kind of situation.

I mean, ya got a heavy truck with a 6.2l engine. It is what it is. IS there an adjustment? not really. The engine draws a specific volumetric flow rate, which is feuled at a (fairly constant) air fuel ratio, assuming you are closed loop, so......not really.

LOL! I was waiting for the heavy truck and big engine comment. Yes, I know it is a big vehicle, that is why I want to get the best possible gas mileage out of it that I can get.
Lately I haven't had as much stop and go and I am getting 16.8 MPG (if I'm really trying I can get 17.4 MPG) so I don't know if I would dare change anything anyway. I feel like there is something wrong. Is it possible to be getting this type of gas mileage from this setup? (yes, the wheel and tire size has been checked and is spot on)

Have you tried the MPG booster tune?
