Tahoe/Burb guys give me some MPG figures
Im not expecting 18MPG, hell 14 would be nice. But after the lift and 33" tires the Hoe is getting 10-11. MAYBE 11.5-12 on the interstate after my last fill up to the hunting camp. For the most part it doesnt bother me, its a big truck and holds everything I need it to in comfort. I only drive to and from work 8 miles round trip but hunting season is going to kill me. I also have about 5-600LBS of tools and winch in the back. Im thinking of trying to lighten it up some but not sure how much it will really help? All maintenance up to date and not throwing any engine codes. I keep it checked as I have a reader.
I think mostly its the 3.42s in the axles that are killing it, it has to shift alot on hills.

33's and 3.42's with a 4L60E's 30% overdrive is killing your milage. You need a set of 4.10's at leats for that size of tire. Most all stock trucks with 265's(31's) got 3.73's. Most all of the 3.42 trucks got 245's(30's). 12-14 would be good if you drive it conservatively. And just because the engine light isn't on, doesn't mean it is up to snuff. ONLY run AC DELCO platinum's or iridum plugs, good 7 or 8 MM plug wires, the blue marine grade cap and rotor, and the updated MPI conversion set for the injectors is another good investment since the stock poppets were crap even new.

If you are interested. I've got an external injector mpi set up for sale. You'll need a wiring adaptor and some one to put a tune on it to take advantage of the setup
