Terry, I had the 3.65 rear gear and hit the 8200 chip before the mile mark and went 162.xxx then put in the 3.40 gear in, but I had a crappy, real crappy, bucking and coughing start, pulled the chute to soon (GPS was 180) and went through traps at 175.250
I am keeping the 3.40 rear gear in and will have a push truck with push plate there to make sure I get a good start.
