Received my Predator, and started with the 65HP tune. I played with some of the other options and my question is that when you are looking at the modified Tune settings, and you go to change them it looks like the defaults are 373 rear end, 95.08 for speed and 260/60-20 for the tires. Well my truck is a 2007 Classic 2500HD LBZ diesel with allison. It is alos 4x4. I have modified the 65hp tune for the correct tire size of 245/75-16, the rear axle and speed are correct as listed. It this just a mistake that I am seeing when I look at that screen. Also am I doing it correctly when programming. I go to the correct screen select 65HP tune after the prompts, I select to modify the tune and just correct for tire size. It loads the tune fine and shows last tune written as 65HP. The manual needs to be better. Who ever is your technical writer needs to flow more in the order of installing the different tunes and not skip around so much and also explain things better.

The tire size displayed in the predator is just a default value. If you did not change your tire size there is no need to change that parameter. The actual parameter for speedo is one number called tire revs per mile, thats why we have to display a default tire size as that value does not give us that information.
Manuals are in the works.
