No, 87 octane was not the fuel economy mode, (which i should have used). I just have an exhaust and my tires are 285/70/17 (i think its 32???), i have i think a 2'' lift. i bought this truck as is, its basically stock.
Okay, well when you run a full tank of gas through her and get a average mpg let us know! Im getting around 250-275miles to a tank running the interstate/city 50/50
