3:23 to 4:10 =retune?

When I switch gears (which will be soon) I'm thinking that I will need to get a retune. My ? is I had to get a crank relearn the first time I got a tune does that mean I will have to get one again? Also I will be getting a g80 is there a break in process I will have to do or can I get in it and put it to the floor?

Yes. Speedo will be off, and abs lights and ebrake light will come on. My speedo is off by lke 15mph. and I had 3.42's before going to 4.10's Crank relearn might need to be done again, but I doubt it.

I assume the g80 I buy will be used will it still need to be broke in and if so what is the process? Also will I need to install the PCM before/after/during?

No break in for the g80 Instal the tune after the gears. Heat cycle the gears probably. Just drive arround for like 30 mins. let them cool for a while, drive arround a litle more, let them cool over night and you should be good.

There's no need to break in a used part. By definition, it's already broken in. Install the retuned PCM after the gears.

Do you really think with my mod's + 4:10's a G80 will detonate? Eventually I do plan on putting a 100 shot on my truck will the g80 not hold that?

Tough to say, but everyone I know here that had one that fragged will tell you not to get a g80.

I was told by my install guy and by Rons machine, that My my gears are pre worn a little, and since I had a used auburn pro, I didnt really have to break them in. But I did just to be safe. in about a week or 2 when I buy the diff cover, ill check and see if there is any metal on the magnet. I would be more worried about the gears, than the g80 on wear.
