The car is my sisters and she just got it the other day, I was kinda anxious to see what my truck would do with it. I was kinda surprised to see how close it was up until about 100! It is from a dead stop! Enjoy!! ‪Tuned 6.2 versus stock g8 gt‬‏ - YouTube The second is from a roll as u can tell... ‪Tuned 6.2 versus g8 gt‬‏ - YouTube

 

Not too damn bad! If you could do something about your lousy aerodynamics you might stay ahead ... it just takes a lot more power to push a barn through all that air than it does for a rocket ship.

 

your sister looks like a man.

 

and it's a 4x4!

 

Thats impressive, makes me look forward to getin a denali. You can just imagine what the diff would be if you had long tubes, full exhaust, and re tuned for it.

 

Ha!! That was my brother driving

 

Yeah I know, I would do that except I use my truck as a hot shot truck and I have put 60,000 miles on it in 8 and 1/2 months. I just wanna try and keeP the gas milage as good as I can keep it, for now anyways! I would like to see the difference with that on it and race my brothers tuned g8!

 

Long tubes a full exhaust and a retune for it will actually help your mileage if you keep your foot out of it even with towing, more efficient/better power and flow will most always net better mileage(espicially after the fun factor wears off).

Id say go for it, what do you tow if you dont mind a side track you use uship to bid for jobs?

 

We deliver parts to coal mines when they break down. We are on call and have to go when they call. We haul anything 5000 lbs and under, with a double axle 16' trailer if needed. Yeah I know it would help but the keeping our foot out would probably be a problem for a while! Ha

 

Yeah trust me it is, in my truck 3500 dmax once i tossed on a 5 inch straight pipe turbo back cold air larger turbo mouthpiece and it tuned i had horible mileage for a while till it wore off, now i drive like a grandpa but i can see 22 mpg highway at 60 now with the 5spd allison and 4.10's i believe and city its probly 17 if i keep my foot out of it and under 2k rpm.
