Traction control kicking in...
#3
Traction control reacts to rear wheelspin, so it will operate the same regardless of power output. It applies the brakes to the spinning wheels and relaxes the throttle until the rear wheels are no longer spinning.

either way traction control should still act in the same manner as it always has.

This is true also

TooSlow02, I'm calling you out on your TCS explanation. On the LS1 cars at least, there is nothing in the entire car that is capable of applying the brakes except your foot. I've gone over the wiring schematics with several GM techs to figure out exactly how it works.
BTW, pulling the TCS fuse from under the hood works real well, does not effect the ABS and is free.

It's kinda rare to make it happen but i'm sure i felt that a few times at least in suitations like that while on light throttle.
It's not the rearend posi unit doing that.
There's a motor looking thing in the back of the bosch ABS module.
It appears to be a non serviciable part, just a R&R item.
I would take a defective one apart to see how it works inside
Have you checked out the brake system digram for a ASR/ABS equipped f-body?

The motor behind the ABS block supplies pressure to the solenoids to make them open and close. They don't apply braking pressure.
The diagrams I researched were specifically for my car. A 99 TA with TCS and manual tranny.
I'm not too familiar with the Camaros. Is ASR what the call traction control?
Right now it's usually the newer, high end cars that get what is called stability control. That is a system which CAN apply brakes to certain calipers to prevent the car from sliding of the road etc... F-bodies do not have this.

I do know for a fact a few new cars comes with adpative cruise control (mercedes comes to mind) that you can set a distance to follow another car in front of you if their speed is slower than your set speed and it applies up to 25% braking if the car in front of you slows down making the distance shorter.
However that won't work well if someone slams the brakes in front of you in your lane out of the blue...

I think The ASR is different depending on the year. I think the LS1's adopted much of the Vette's fly by wire ASR without being truly fly by wire. I know if I hammer my 01 LS1 with the ASR on the gas pedal pushes back. I know for sure that the LT cars's ASR uses just the brakes but I'm not sure when the change over to the throttle by wire happened on the LS1 F-bodys because there is for sure some serious backpedaling going on in my LS1's ASR.

OK, first of all "throttle by wire" means elctrical wire, not cable wire. The C5 vettes got a computer controlled throttle body, the f-bodies didn't. F-bodies were all cable driven. They are very different from the vettes. When you think about it, there is no reason for the vette pedal to be pushed back. I don't ever remember it pushing back, either.
The throttle pushback you are refering to is caused by the TCS motor which is mounted behind the battery.
When TCS activates, it first reduces timing to reduce power. If that is insufficient, the TCS motor will physically close the throttle and you feel it pushing back on the pedal. The automatic cars also have a torque management system to reduce force to the rear wheels, but since I have the M6, I didn't go into detail on how that works.

yeah I re-read my post realised my wording was all screwed up on the throttle by wire thing I edited it a bit too late.. lol. I'm all hopped up on nyquil right now with a bad cold.
Your post totaly makes sense I'm just out of my mind right now.
