well, i'm on the gas a lot sometimes and I think the Gas Milage stayed about the same. I havn't really gotten a great chance to test the milage out on the highway. My 4.6 averages around 15-18. 87 was 1.85 a few day's ago, so if 91 comes back down to like 189 sometime I'll prolly switch over.


Oh, i'll post a vid of my rear tire on the shifts soon.
