Yep, that's exactly how it works. I don't think stability control doesn't work well with a limited-slip differential, but it sort of makes it unnecessary. Why bother with the extra hardware in the differential if the truck's brake system makes it unnecessary?

Hey everybody just wanted to let you know we can eliminate to speed limiter for track use. With that tune we also got a consistent 13.6 at 100mph in the 1/4 mile. Some of our customers have reported faster than that but that is as fast as we have achieved with a tune only.

Hahh "track use" I love it! What kind of wheel/tire dimensions do people switch to for that? Any popular suspension changes?
..reminds me of a time I had my rear tires at 80psi, while I was unloaded. As I neared 90mph, hit a typical bump on the expressway, and I think the back end actually left the pavement for a second, and landed an inch over to the right. It didn't really throw me off track or anything, but I rarely go over 75mph now. and I keep my rears at 65psi.

I think LS might actually decrease stability and/or traction in some low traction situations. Think about making a turn on ice. You don't want inside and outside tires turning at the same RPM.

This is why I think it's a terrible idea to engage the locker when driving in bad weather.

For normal day to day driving, I agree. But there are some situations where having both wheels spinning, without brake control on one, is advantageous.

The average driver today would easily loose control of LS or mechanical lockers on slippery roads. I used to love driving my old Scout II in high school. With the Detroit Locker rear end, lots of sideways tire smoking fun on old bias ply Goodyears.

Wow I guess I am not an average driver then. I own three Ford trucks and a 500HP supercharged Mustang. All have LS. One of the trucks has a Detroit Truetrac. And I live in snow country (Mustang stays coralled in winter though). Also I've never owned a front wheel drive or all wheel drive vehicle.
