Launching PSD

Hey all, just curious how you all launch your trucks. i've got a 6.0l torqueshift PSD and i launched it in 4x4Hi the other day, racing my buddy who has the Edge box with Attitude. she spun all 4 it felt like, then i heard a loud pop then she went.
Stalled it up to about 1500 then let off the brake and put her to the floor. Anyway, the pop concerned me as i don't want to lay the tranny, or any part of the tranny on the ground.
How do you all do it?

I spool up to 2100 and let her eat. 80k miles here.

2000 rpm is the sweet spot though.

The "POP" may have been the front hubs engaging

I've had my truck do that before, (not on a boosted launch though. )

I always switch to 4wd while stopped, then let the truck roll forward a little to lock the hubs. I hate that clunking sound.

I am not sure about the popping noise. Maybe its just the axles spinning till they hit the hubs?
