I just got off the phone with the off-road shop and they are ordering my gears today. Looks like Im actually going through with this 4.88 swap. I put a few hundred miles on her this weekend and according to the EVIC I got 16.3 MPG at 70-75mph. On a normal week driving back and forth to work, I average about 14 driving the same speeds, but thats not just cruising and the terrain is a little more rolling than I was on this weekend. I know I can get 14mph easily around here, because I ran it in 5th gear for a while and got the same milage in 5th as I did in 6th. I know I dont drive a Prius, but I still like the idea of getting in the high teens on long tips. Im a little concerned about what its gonna do to my fuel mileage on trips like what I took over the weekend, but obviously not enough to keep me from doing the swap. It is what it is I guess. Looking forward to seeing what she'll do when I get it back. She is scheduled to go in for the swap first thing Wednesday morning, and I should get it back Friday evening. Just had to share.
