So I cant really afford the down time of a custom tune and was thinking of a little programmer preloaded. I have heard good things about the diablo intune, I'm just really looking for a little boost in mpg and the torque management reduced some but not so much that the reliability of my trans is reduced. Also is anyone running a Jones Turbine or Aero Turbine muffler like a 3535? I am debating on exhaust, more for sound than anything, and have seen where people talk alot about them but not so many videos of them. Thanks for any input and the truck is bone stock. I'm averaging 17mpg hwy and 10 or so in town but I put about 3k miles a month so 1 or 2 mpg would be alot of money saved in fuel per month.

 

When my truck was basically stock aside from the lift, gears and 160* tstat, i had a hypertech programmer i had really good luck with.... Gave me quite a bump in mpg, and all around sotp dyno was much improved!!!

 

There's no down time to a efi live custom tune from blackbear. You log data and email it to them. They send you back a new tune to load. Work well and its tuned specifically to how your truck runs.
