Competition driving mode
I was asked a question today by an owner of a 2004 coupe with AH. He wanted to know what changes in the car when it goes to Comp driving mode on the DIC. He activated it by pressing the AH switch. I have a no option 98 so I can't answer his question. I told him I thought it changed something in the shocks but don't hold me to that answer. I knew if I asked here I'd get the correct answer. Thanks.

In simpler terms, comp mode maintains the vehicles ability to brake each wheels individually to maintain a straight and controlled course.
And, it disables the throttle control that reduces throttle when your wheels slip. (activates when there is a difference between actual vehicle speed and wheel speed)
Only by selecting the "off" mode does it eliminate both of the above features.

When in "normal" active handling mode, if the car spins or plows, along with applying the brake to one wheel, the engine's power is shut off, either by cutting the fuel or the spark. This dramatically slows the car down and there is a couple second delay before you can pick up on the power again 
. In Competition Mode, you can get back on the power immeadiately. CM may also allow a little more yaw if you are in power induced oversteer.

Torque management is only on A4 cars in an effort to prolong the life of the 4L60E tranny. In GM's opinion, it was not strong enough so they put in a program to reduce engine torque between shifts and in other areas of the power band where tranny damage was likely to occur

He explained that it was orig. in A4 cars but was also implemented in the manuals to reduce wear and tear on the tranny.

I have no idea how it actually accomplishes the power reduction. I would guess you are right and that it would simply pull timing, but I do not know for sure

I did not know they ever put TM on the M6 cars. I wonder why they would do it in later models but not early ones

Comp mode gives you maximum torque at rear wheels at all times, while still saving your A$$ from going out of control or in a spin... That's the easiest way to explain.
Drive carefully...

Here's some reading material, if you so desire.

Electronic Traction Control
A full-function traction control system is standard in every Corvette. The system limits wheel slip under power through brake intervention. If the system detects that either or both of the rear wheels are spinning, it will brake the wheel until both rear wheels are rotating at the same speed. The system can also be shut off, if desired, for certain road conditions, such as deep snow.

OK...Because today in a "cranky Friday" to me, I'll answer this way:
Doesn't anyone have an owner's manual anymore?
It's explained in full detail. Read the freakin' book.
