Was wondering with those out there with a tune, preferbily by hp tuners, what do you get for gas mileage? Or has it helped out much?

I just got a tune by a local guy where I live, and was wondering if I should expect a increase in gas mileage.

 

well, we're not exactly compairing apples to apples...(RCSB)..but i am currently getting 15.4..keep in mind all of my blt on's.....stock my truck avg. was 19.2

 

Was the mileage you got when the truck was stock, was that with a tune or without?

 

19.2 was bone stock with no weight reduction
