between 300 to 350 miles to a take city driving
highway driving more like 360 370

It would be cool to see someone with tunes to see a difference I pick up my daughter 275 miles away every 5 weeks so it's the reason I'm asking. I'm considering bolt ons and a tune

 

[crazycoupe]

6.0 swap, LTs, cold air 350-400 easy driving BTW

 

[ccapehartusarmyINF.(ret)]

a tune on a stock motor your going to see little to no MPG improvement and its expensive
there is plenty of things that you can do to improve yer mileage that cost next to nothing before get to tuning
make sure yer tires are always inflated to the proper pressure
get yer alignment done
are yer shocks good
stay on top of oil changes
drive with yer windows up (driving with yer windows open or down can have a drastic effect on fuel eco)
on a long trip set the cruise control and leave it
clean yer maf and yer throttle body

250 miles or so 4:56 gears killed my mileage.

 

[ccapehartusarmyINF.(ret)]

OH yes 4:56 will definatly kill yer MPG
i couldnt imagine running 4.56s on a tahoe you towing yer yacht behind that

07 Denali, 33x12.50s, Blackbear tuned, 300 miles.

 

[Sasquatch]

05 yukon 93 octane blackbear tune cai and catback 3:42 gears with 275/55/20 tires. 380 a tank. I rarely get to drive over nice flat land but when i do i get over 400. The worst thing that i did for my MPG was getting 20 inch wheels, I lost 1-2 mpg with them.

 

[t_ahan]

225 miles city/hwy 93 octane best ive done with the current motor build was 345 miles.
i will try to see how much better i can get i mostly see 5-7 mpg city, 12-15 mpg highway.(heavy on the throttle,i know!)

03 denali with the usual - 22"x12"wide SS Reps(pretty heavy)
only thing left oe right now is the fuel injectors and fuel pump, once i get the fuel system done im sure i will see something different!!
getting 8.1L injectors and will re-tune after

before i touched GM's set up i think i remember getting like 12mpg city and like 20+ hwy!

[1clean08denali]

Cluster says 430 when I fill it. Average MPG says 16.2 when running 93 so the math is pretty close. I'll have to actually measure one of these fill ups. Everything is stock and I'm on mostly on highway & rural roads. AWD and 18"s.

 

[08grey]

Bwahhhaaaa. 400 miles. My cluster says do you really want to know?
