Just purchased a 07 Denali for the girlfriend. Looking to learn a ton off this site. Purchased it out of Portland...about a 300 mile drive haha but well worth it for a one owner clean denali
I believe it needs a new set of breaks, also wouldn't mind getting a set of shocks for it not sure what kind yet... Also want to help mileage as much as possible I know it'll never be awesome don't care about that but a extra 1-2mpg can't hurt! Plus I just have something wrong in my brain because everything I own gets modded haha! Which leads me to believe joining this site was probably a bad idea...or not! Already have a V2 for the duramax so some efi is defiantly going to happen soon. Intake and exhaust also hopefully...
What's everyone getting for mileage with a tune and intake/exhaust?
Any advice or tips, welcome to hear them!
Thanks guys for the awesome site. Hope it helps me learn as much as the duramax forums did!
