[QUOTE="tj04cobra, post: 11125033, member: 73436"] Which tunes do you have? If you have the 345 tune, load that. I think you will like it. The daily driving with it is awesome and the power is there when you are ready for it. The fuel milage will be decent as well. I can't explain why, but the hotter tunes get the best milage. My 6.0 got 15-16mpg hand calculated with mixed driving when it was stock. I took a 420 mile trip about a month ago. Filled up when I left and filled up when I got there. I hand calculated 20.3 mpg at fill up. That was with the cruise set at 70 the whole time. Now that I have the powermax turbo, 4inch exhaust and Gearhead's extreme tune, I'm going to start logging it again. I think it will go up a little if I keep my foot out of it. [/QUOTE]
