and i cant be happier. my truck is an 01 suburban with 5.3L and almost 300K miles. it feels like it did when it was brand new or better! on the way home from getting the tune done yesterday i was hitting 80-90mph easily! not that i speed, just felt i needed to see what the tune did and man was i impressed! today it seems even better! Justin, you are the man! very pleasurable experience. i'll be calling you in a few months when i get my headers!!

Cool man! The thought just occurred to me so I thought I'd ask
keep us posted as you continue to drive it 
also, I've known several 300k+ miles GM truck/SUVs. My dad is one of them with a 92 Sierra he had and bought new. He also bought an 85 s-15 he bought new and put 300+ on it. As said, it's all in how you maintain it....
