A fellow Z06er recently "informed" me that switching the T/C into competitive mode (on the dyno) results in the motor producing more HP.
Does that sound right?
I can't notice a difference.
It will only be an advantage when It's warm and you have traction because the trac.controll won't be cutting In and you will see the most performance If you have traction. No gains on the dyno
Some people here are confusing AH and TC. They are two different things. TC comes off when I race or dyno (competitive mode). I don't see a reason why you should turn AH off unless you are in a drifting competition.
Comp Mode can save your life. It did mine. Ranger's arguements are vaild unless the physical laws of nature no longer apply. Active handing is an engineering marvel and I'm dam glad we have it on our cars. I myself have noticed no difference among the systems in way of acceleration, handling, well thats another story. JMO
Competitive Driving mode is benign unless the steering position sensor and the yaw sensors disagree on the intended vs projected path of the car. Then and only then is countervailing brake action triggered. That's not a condition you are likely encountering on the street.
Many thread in the archives on the perils of street driving (or drag strip) with Active Handling turned off. Suggest new owners read a few to become aware of the risks involved in turning the system off.
Comp mode limits the worst that can happen but has no adverse affect whatsoever on the acceleration of the car in straight line.

That may be true for driving in a straight line (80% of City, Rural and Highway) but not on road courses. I drive with it off 98% of the time.

I drive with it off 100% of the time. I found that it wanted to try and drive the car about everytime I go somewhere. I don't need any help. One of these days I will go ahead and have someone edit the indicator lights out of the PCM, yank the whole mess out of the vehicle, and replace it with a proper kevlar line system. If I had the time I would have done that when the EBCM failed last time.
I have not noted, however, any difference in the throttle, engine, etc, by switching between any mode.

Having ridden 412 miles on a sportbike today, I certainly respect motorcycle roadracers BUT I find the above statement very hard to believe. For AH to come on "about every time I go somewhere", you must be driving like an absolute lunatic. I have about 20,000 miles total time on 2 separate 02 Z06s, and I don't recall the AH coming on EVER on a dry street. On the roadcourse I try to stay out of it, but it comes on about once a lap or so...
Sounds to me more like you hate AH with a passion (which is a perfectly valid opinion) and that's what is coming out in your writing; instead of an actual observation...

The AH turned on when I was struck twice by a semi truck turning into my lane. The car was fighting my wife (she was driving) as it was forcing her to go straight into the underside of the tractor, I had to reach for the wheel and help her force the car to the shoulder. The rear tandem tires literately sheered off the rear fender, entire driver door, front fender and hood going into the cockpit because the car was slowing down because of AH and the truck wasn't. The end result is that we both survived. Its not that I hate it with a passion, AH is great for most of the time on slick wet streets but in my case on a dry sunny day, it was an hindrance that was almost proven fatal.

I guess all, any of us have to report, is the perception of our experiences. In 20,000 miles (approximately 1,800 of them on a roadcourse) all I have to report is good experiences with AH.
Most everyone I personally know that drives a street Vette at my HPDEs, drives in Comp mode. At least 2 of them turned it off, spun off the roadcourse, and decided to always keep it on after that.
As with most differences of opinion, it is pointless to argue. You are never going to be convinced that AH is good, and I am never going to be convinced that AH is bad...

I have 86k miles on my 2002 at this point. And yes, some people think I'm a lunatic - but they also can't take a two wheeled vehicle with a tire contact patch the width of the palm of your hand and absolutely no computer help around a race track in a down pour that's limited visibility to the extreme with 65 other professionals and stand on the box when it's over. If they could, they would understand how really trivial it is to drive a Z06 beyond what the engineers programmed the active handling to perform and into an area the chassis and suspension will absolutely support that the computer if on will try to prevent. It wasn't made for all of us. We've covered this topic over and over here throughout the years. The system is great - if you need it. If you don't need it - it can kill you. If it malfunctions - all of this is out the window.

Good luck to you.

I'm not stating that AH is bad. As a NASA/NCM Instructor I believe it is a very good thing for inexperienced AMERICAN drivers. What I am saying that there are certain situations which AH is far from a good thing. A good seasoned driver knows the limitations of his vehicle and has a realistic understanding of what he/she can and cannot do. The reason I believe AH should be turned off when on a road course because it masks the limitations of the car and has a tendency to give inexperienced drivers a false sense of infallibility. The idea of HPDE is to teach the driver to be smooth and most important consistent. To accomplish that is to gradually learn the limitations of your car on a very safe track. What made me a smooth driver was and continuing to learn from my mistakes on the track. Besides you haven't graduated until you've spun out :-) Its the ones who never experienced a mishap on the track are the ones who really haven't learned their limitations.
