Who needs a speedo gear when you have on-board GPS?

CRASH

I don't even want to know what your calling a GPS.

4.56's with 32's and a bad miss are getting ~19 mpg @ 70mph on the higway

33" with 4.10 and a AW4 this past weekend I was getting just over 20mpg on the highway. I do average between 17-19.5 on the highway. It really helps to change the speedo gear to match. Juice

I'm running a 85XJ lifted 6+" on BFG TA/KO's w/4.56 gears and a 4.7L stroker. At 65mph I get about 21mpg, at 75mph I get about 18mpg, at 95 I get about 14mpg.
