I've been running the default tunes with the s1m trans tuning... After a 4 inch lift and 35s the shift points have all changed. I'm just curious which tans tuning people with lifts are running.

I'm just tired if driving 55 mph with my truck screaming at 2000 rpms. And I would prefer to prolly run an s2 tune so my torque converter isn't locked in 4th.

I had the same issue. 4" lift and 35's and it would scream at 55 MPH. I'm on the S1L tune now, and I love it. I think my MPG's will be a little better as well.
