SCT X3 parameters.

I can't find the original thread with the SCT options, so I will ask again! I can't remember what to set the wheel rotation to for slightly larger tires, i think it was 500 and something. I can remember that its 3.73 for the gearing, and shift pressures are around 5-10 % but I'm not totally sure.

Check on your tire manufacturer website for the brand of tires you have, they should have specs including revs per mile listed for each tire size they sell.

I have 37's with 4.30's and mine is 565. 38's are like 550. So if you're smaller than that you are closer to 600.
