If I get one, i will keep it close to stock as possible without changing intake and all that.. anyone got stock trucks that get good mileage?

Well bone stock I was getting 16 around town and 18 on the highway. With just a programmer, PVC reroute, Egr blocker plate, and stock air box mod. I was getting 20-21.

I have a 2005 2500 cc 4x4 that I run a big power tune for better fuel mileage and I get around 18 city and my last road trip I got 26 on the mostly highway. I drive trying to keep the rpm's below 2000 and boost below 5psi around town, its a bit slow but it works.

Did you get 6th gear unlocked? I'm sure that will keep the rpms in the sweet spot and be able to go 70 mph.

So you have a stock motor and just have a tune and can get 26 mpgs out of it?
