Hey guys, I've seen a few posts about stacking chips/programmers. My truck still only gets about 15mpg if I baby it with the XZT. I cant tell any difference between the stock setting and the economy setting. When I switch it to high then the truck does gain HP but not the so precious mpg's. :thud: Is there a programmer that would be good to stack with the XZT? Any help would be appreciated.
