Hey guys, im about to order my nelsons tune and i have been bombarding allen with questions i feel bad so i would like to know what you guys think and i have a couple questions.......any advice would be much appreciated.

ok i have a 2000 2500 with the 6.0.....only mod is k&n filter, i figure thats worth at least 85 rwhp anyways, my other truck has built motor and all the goodies and i want to pretty much leave this one alone...its my daily driver and i want it to remain very reliable, im not looking to win any races...just a better tune that i have read so much about. right now im leaning towards the dual 87-89 tune set up for economy....seems like everyone that gets the dual tune likes it and then steps up to the 93 hot tune 90 octane is as high as we get at the pumps where i am....and if im getting way better results with the higher octane i can always go for a 90 tune later.....so what i would like to know is what do you guys have, and what have you noticed, power wise, gas milage.....how much tm did you get removed, stuff like that. im going on a 10,000 mile road trip mid november and a few miles per gallon better would make a huge difference!

when i get the new pcm am i going to get whatever the milage was in the last truck it was in or is that something that you can specify?? thanks all
