Thanks hellbent, did an rpm test today on the ride to work. @ 70mph I'm running 2050 rpm and if I set the cruise control I get 21-22 mpg at 65. I see people post rpm's of 2500-2800 at 70 with very little milage loss and I'm very skeptical. The math doesn't add up to me, how can you run 35-40% higher rpm's and not lose milage?
My engine is basically stock with the exception of the 703 injectors and some minor intake/exhaust mods and I have no problems with acceleration or freeway milage.
However my around town milage isn't very good with the 3.07 gears.
The 8.8 already has 3.73, I will have to re-gear the front either way. I'm gonna try the 3.73 first and if I don't like it, I can them swap the rear when I do the front.
It's a win-win either way.
