ProCal Tire/Gear input

[xzsawq]

Hi everyone,

I just bought a 2024 big bend 2.3 automatic

It has the option “4.27/REAR AXLE-LOCKING DIFF” on the build sheet.

I also installed ProCal and the tune makes a huge difference.

The tires are 35x12.5x17 (revolutions/mile 597, Baja boss)

My question is: in ProCal under tire/gear for the gear section do I put in 4.27 or do I leave it stock because it’s an OEM factory option?

Just change the tire revolutions, do not change the gearing.

Anyone know what the stock value is? Also working with ford tech support to get the stock tune to work, as right it seems to give me an error when trying to revert back to stock. lol
