Hello,

Just received my MPVI Pro unit and did some basic stuff like disabling VATS for my Vortec 5.7 swap but when trying to change the gear ratio down to 3:07 from 3.42 noticed the tire box in the Gear/Tire wizard it reads 0.7 which is weird so question is how to do this? What 0.7 for tire means? If donor Suburban used same tire size then just input 3.07 for gear?

Your help will be appreciated.

Using 3.6.26
