Johnny are you asking about the stocker or the tru trac? The tru trac is MUCH heavier constructed and can take a beating far beyond where your stocker will fail. It keeps locked while going straight and only slips when in a turn. It is pretty solid and I have yet to have it slip while straight with some pretty darn hard launching that I do. Whereas, I slipped the stocker all the time and flat out broke it three times.
The TCS you're referring to is related to wheel spin. When the system senses one tire spinning faster than the other it compensates.
If your running around with a CAI and tune and some minor mods - no - I do not think it is a neccessary mod at all. Pushing any FI and making some torque - absolutely a mod to have IMO.
Installation of the Truetrac is simple if you are already doing a gear install. If you're not doing gears at the same time, it's a pain. Installing a new differential is like a gear install and then some.
An LSD and Traction control do similar things, sometimes. However, the advantage to having a better LSD is that it can speed you up by delivering power to the road. On the other hand, the traction control system can only REDUCE power by applying the brakes or by shutting the throttle.
In addition to being more durable, the Truetrac has a higher bias ratio than stock. To explain it simply, that means it takes an even larger difference in traction before it will begin to slip. For example, an open differential might slip 80% of the time in low-traction situations. The stock trac-lock is better and might slip only 30% of the time. The truetrac is better still and will only slip 10% of the time (for example). A true locker will never slip (0%) but they are loud and uncomfortable for street driving.
Another advantage of the Truetrac is that since it is gear driven (it is a Torsen type diff....Google it), it never truly slips. Even when cornering it delivers power to both wheels.

All you guys seemed to explain it is better but not what they do.

what does the LSD really do? help you exit turns faster or w/ less slip? but isnt that what tcs is for? i know i sound like an idiot but i have a feeling im not the only one question this (alteast i hope so, lol) and are they worth it?
When your in a sharp bend what tends to happen is the power is split evenly or fairly evenly between the 2 wheels. So because the inside wheel in a corner is getting just as much power it tends to be spinning just as quickly and this is why you sometimes see people lighting up 1 tyre mid bend.
The LSD allows the power to be transferred across to keep things better balanced and reduces under and oversteer and gives better traction.
