Has anybody found a kill switch for the slip dif, or does the VDC button take care of that?

I don't really understand your question, but turning VDC off will allow your tires to spin, thus engaging your VLSD (which I believe is what we have).

the diff is mechanical, not electrical.

Theres a yaw control box under the center console (next to the e-brake). Put an inline switch in with the orange wire that essentially "cuts" it.

I honestly can't think of any reason NOT to have an LSD working all the time.

I have an automatic, and every time i floor it form a stop, the slip kicks in and increases the throttle response time. I just wanted a way to fix that.

That's not a limited slip differential. That's traction control.

Limited slip is a mechanical feature in the rear axle that send power to both wheels. The alternative is an open differential which doesn't transfer power between the two. So if one wheel spins, it just keeps spinning and no power transfer to the other wheel. In a limited slip, there is a clutch that "drags" the other wheel as well. So if you spin up one wheel, the other wheel still pushes forward.

What you are talking about is the traction control system engaging. When it detects wheelspin, it engages the brake, reduced fuel and timing and may reduce or restrict throttle response.

There is a switch on the left side of the dash that says VDC. Hit that and the VDC off light will light up on the dash. It won't completely turn off traction control...but it does reduce the limit.
