Have the new 87 octane e-tune down loaded into the Power Wagon. Damn....feels like a new truck.

Got a lot more low end torque. Gas mileage is going up, if I can keep my foot off the loud pedal.

Once I burn through this tank of 87, and 2 tanks of 93 octane. I'll do the 93 e-tune. My truck always felt like a dog from day one. Now it's running like it should have.
