OK just got back!!! OMG!!! Same road, Temp about 8deg cooler today but a little bit of wind today. Rest computer same place, brought up to 68mph put cruze on and went 28mi turn off cruz roll up off ramp.

Stock.............. 12.0 MPG went from 11.9 to 12 as I stoped.

H&S full delets. 21.6 mpg

I can't believe it myself!!! Now I know 28 miles is not the tell all but no matter how you slice this it kicks ***!! did a lot of back roads some big hills and made 7 stops and only drove about 5 miles on the highway on the way back and I got on it a LOT the rest of my trip, did 77 miles total and the computer says 17.3 right now.

Needless to say I am VERY happy.

PS this was on the wild setting also.

 

Awesome, I am happy with mine also.

 

The next step is to get a fass/air dog fuel pump to keep all the nasties in the fuel from fouling up the injectors and ruining your day. Good job. My truck has been deleted for over a year. I was one of the first guys to delete a 10 truck. Warranty sucks any ways, my rear diff seal is leaking. I only have about 14000 miles on my truck. There is no way that I'm going to take my truck to the dealer so they can ruin my truck. I bet I'll have the seal replaced in about an hour anyways.
