Wow, you guys get some killer mpg's! I've only had my truck long enough to be on my fifth tank of gas but I'm averaging 10 in town. Lot of stop and go short trips.
Doesn't look like I'm going to be able to hit the highway with my trailer until the 1st of June. I was hoping I'd be able to cruise along at about 70 and average 10mpg. Doesn't look like thats going to happen.

I took a trip down into the city (Philly) today and got 16 driving through the city, which was a lot of stop and go today. Filled up when I was leaving the city to come home and got 22 on the highway for the trip home. I am running the SC 91 tune along with all the other stuff listed in my sig.

I reset mine at every fillup and then check it against hand calculation. The computer has read 1/2 to a full mpg higher than hand calc.
The numbers I gave in this thread were my hand calc #'s.

Im getting like 9-10 mpg since I put 22's on but the overhead display is saying 18.6 so yeahhhh. There is only 1/2 inch or so difference from my old 20's and tire to my new 22's and smaller tire. I need to get it tuned I guess
