If the code is confusing the easiest way is to lift the rear axle off the ground ( safely as always ). Release the ebrake and turn one wheel. If wheels turn in the same direction, you have posi. If one turns in the opposite direction, peg leg ( old saying for regular differential ).
Thanks 6gear for the code breakdown!

You are right on a posi but I think the G80 Gov lock units will act like a regular differential untill you turn one tire fast enough to activate the governor

I guess this is a two-part question, also what shift-firmness should I be aiming for?

if your truck has the traction control option all you have to do is push the button to turn it off. as for shift firmness, i wouldn't do it with programming. i'd install a good shift kit with billet servo's.
