Re: Supercharge or gear swap?
Screeper, what did the gear swap cost you and who did it? Is there a carrier break to go to 4:88's (did you have to use new carriers)?
How bad does the mileage drop off after 70? I drive I-5 a decent amount and 70 is the limit. If I drive 70, I get run down by big rigs! 
My good ol Dodge, cruising at 90 on 5 and getting 16mpg. 
Oh well, the Hummer is like nothing else!
