Installed 5.38s and Spicer Ultimate 44 FDU and Extreme CVs 32 spline

Kept same gearing so sounds like I don't have to do anything. I also have Forscan so can tweek things with that. Main thing I was wondering is about doing a relearn if the system now has to recognize a different part number installed. Guess it wouldn't hurt to just do that anyway.

if the gear ratio is the same there is no difference as far as the computer or transmission are concerned

Yep, what @Brian_B said. Other than if FAD is a factor, it doesn't care.
