| Performance Ready I have a 2007 LBZ i just cut the muffler off and have afe stage 2 intake. I'm ready to get more out of my truck plus more out of the diesel that goes in it(avg mpg17). At anytime during the day/week i could have up to 30k behind it. So there are a few things i have to think about. Also anyone notice that with a load the 2500hd leaf spring aren't strong enough so any useful info will help(I'm kinda new to diesel performance) Thanks |
