i really just want to see if the mileage mode helps out at all, i KNOW gas prices will go back up and if it makes a difference it could be a good investment
mileage on the superchips isn't as much as its cracked up to be...i was getting like low 18's to mid 18's and then put it on performance so i had to use 93 but i got 20.4 on the way back to school today plus the extra power so i'd say its worth it if you ask me...i've heard its not as good as the 50horse/60torque they claim on the 5.9 but i have a 4.7 so i don't know just going by what i've read
it says 91 or higher but i put sheetz 92 in and it pinged like a mother ****er could have been bad gas or something but i've just avoided sheetz or wawa everytime i've filled up and put 93 in from now on i'm sure you could get away with whatever and i know the elevation does affect it isn't your regular 85 bryant?
