Re: Supercharge or gear swap?
I personally would go for the supercharger. After I did my lift, I installed 4.56's. My gas mileage picked back up because the truck didn't have to work so hard to lug all that truck around.
Though it helped, at 70 mph, a minor incline will cause the truck to go into OD. I personally can't stand the performance at highway speeds with the gears... God forbid I'm pulling my enclosed trailer.
At some point I'm going to install a supercharger but that's my suggestion.
HTH's,
Mark
