Hi guys, I just got a new to me '08 F250, 6.4L, low miles, well cared for, crew cab 4x4 that I'm loving but the mpg sucks! Friend of mine has a 6.4 too and he gets a lot better mpg with a similar truck. His can get close to 20 mpg on the interstate and I'm only getting 12-13! I bought mine with the *** already ******d from a dealer but I have no idea what kind of tune is on it and there is no tuner that came with the truck. How do I go about getting a better tune for this truck that will give better mpg and what tune package would you veterans recommend? I'd like a mild tune for a ******d ***, with safe HP levels to tow if needed and the best mpg possible... Thanks for any advice!!:rockon:
