auto 37's and 3.73's. I'm at 2200 rpm at 65mph with o/d off. It's ok... but takeoffs are rough. 5.13's go on real soon. Came in this week.

I just ordered the AEV Procal so I will let you all know how it is after you correct the speedo and shift points as soon as it gets in.

Anyone running 35's & 3.73s with a manual? If so, same issues or is it livable for a daily driver?

I am running 4:88's and 35" BFG's on my automatic with the Hypertech power programmer and it is the best thing that I have done to mine. I have NO problem powering through mud,snow or even pulling my quad around on a 8' trailer on the highway.I would recommend this setup because it still gives me "good" gas mileage 15-19 on the average.

I think I may should have gone 4.88 over 5.13 with my 35s. I only went 5.13 incase I go 37 and to have a little more juice when scooting around town. I am at 2k RPM at 55mph now. But my tranny goes into OD super quick.

OD was non-existant with my 4.10s... I don't know how you can stand it with 3.73s. I would be afraid I was burning up the tranny or something.

I got my AEV Procal in the mail today so I will have to try it out and see how changing the shift points does. I think one of the biggest things is where you live, what kind of terrain. I am in college at Roanoke College and it is very hilly around here. If you are somewhere where it is flatter, 35s with 3.73s would be a lot better. They aren't that bad on level ground, but once you start going up a hill they are terrible, always downshifting and searching for the right gear.
