burnouts with a factory locker.. is this normal?

i have a disc brake rear end out of an '02 Z28 in my 86 that has the factory locker and 3.42 gears. i've been driving it gently since i put it in the car this spring, but today i decided to do a couple of burnouts because why the hell not... i have noticed in the past that it kind of chatters and shudders until it figures out where to send power if i give it a bit of throttle when making tight turns at low speed and have gotten used to it, but when doing a full on burnout it feels like it sends power to each wheel one at a time until the speeds equalize then it does a nice smooth burnout.. the rear of the car kind of moves to the left, then to the right, then stays straight...

is this what a locker is supposed to do?

every other performance car that i've had in the past has had an Eaton clutch style posi in it, and they just roast both tires at once with none of that side to side weirdness..

Stock in 2002, assuming no SLP upgrade, is a no-clutch-preload Torsen gear bias diff.

That sounds like something they do, yes.

My car always used to do that. In fact it was so violent it felt like the wheels were coming off the ground one at a time. (a fairly stout 400 motor)

But then I got a set of LCARBs.

Then instead of "burnouts", it HOOKED UP AND WENT.

that's what i thought. it just feels weird to me- if i get in it and don't do a burnout, it just flat hooks and goes..

and, no, i doubt it was an upgrade. it came from a convertible that was owned by an older guy (mid 50's) that only put 50,000 miles on it from the time it was new to getting hit in the right front corner by a guy with no insurance that blew a stop sign last fall.
