i've been hesitant to get a tuner because i didn't want to have transmission problems, well recently my tranny died with a stock truck. figured since it has to be rebuilt i'll go ahead and have it upgraded a little. Now that it's upgraded i would like to get some better mpg with a tuner, best i've seen so far is 13.5 with the wife driveing and 7 while towing my 34" fully loaded gooseneck. what tune should i get? I'll probably set it on that tune and forget it. i'm not looking for more power, just want better mpg without hurting tranny or engine when i decide to tow. I just want a general tune for everything, dont want to constantly be changing stuff.
