Power and gas mileage.. Should I change tuners?

I have an 01 excursion lifted. I like the truck but not to happy with the power. I have an intake, mbrp exhaust, and a superchip. It just seems slow. I currently get about 12mpg in town with 6" lift and 35s. Would I feel to much of a difference switching to something like a ts chip. Any suggestions?

dont get a standard ts chip. get one with custom tunes.

Ya I was looking at the tony wildman but I thought it would be harder on the tranny because of the more power

well he is better at tuning the tranny as well.
so still better than the chip you have now.
you could could get a new valve body for the tranny that helps a lot.

Another thing worth mentioning, are you taking the bigger tires into consideration while doing calculation for you mileage?

On my truck the speedo/odometer is exactly 8% off with 35s

My speedo is off by 9%. I get anywhere from 12-13 in town. and 15-17 on the highway. I have a 6" lift 35s and a TW custom tuned chip. I try to drive sensible but that can be hard lol. The mileage I see I feel is pretty reasonable for an 8k lb truck lifted up with big tires. You can see what I have done to my truck in my sig. The mileage is starting to get to me, and that's why I'm gonna be buying a diesel jetta for a commuter car. But I will NEVER sell my baby!!

Bingo! Recalibrate the speedometer to the Revs per mile rating of your tires. Run 3 full tanks through and then recalculate your fuel consumption average.

The mileage I'm reporting is taking the 9% difference into account. If I was just going off the mileage my odometer read boy would I be hating life lol. My 12-13 in town is with the correct amount of miles driven. I even used my brothers GPS to double check over a series of fill ups.

What mpg are you expecting out of an 8000lbs truck? If you are expecting good mpg get a v6 half ton, you drive a truck that will pull whatever you want why would you expect good mpg?
