Wow, 4.88's?!?!?!?! I put 4.10's in the mustang and thought I was a bad ass.
I can't believe your mpg's didn't drop off. How much top end speed did you lose? or can you still (theoretically of course) get it to 120ish?
Yeah I was shocked the mpg's didn't drop as well. It'll go plenty fast for a 6,000 lb truck. "Theoretically" I haven't noticed a difference on the top end and it's crazy torquey down low.
