CJ,<br>I'd love to tell you that I have the TC in my car right now but I DON'T. However, I have ridden in my friends car that DOES have the TC so I CAN answer all your questions. First of all, to install the TC you should look around anywhere from like $300 to $500 dollars max. It's about a 5 hour job! Give or take a little depending on how well the installer knows how to do it. Second of all, the VSC is the Vehicle Skid Control. This system senses when your car is in a skid and will correct the problem by redistributing power so that the rear wheels don't break loose. If you turn the system off, you'll see a litle red light come on on the dash that says VSC off. In this mode, the system is not being used. So it won't correct for your skidding the tires. Which is wonderful if you love smoking your tires like I DO!!! To get your fastest 0-60 times you put the car in POWER mode and turn the VSC OFF!! When you turn it off, you won't harm or disturb any other components in the car, all your doing is telling the computer, "DON'T FIX IT WHEN I PEEL OUT." Now in regards to the question about "was it worth it?" I would say a resounding, "HELL YES" My friend loves it and thought it was the best money he's spent in a while!! I would agree w/ this whole heartedly. I'm going to get the TC extremely soon. My father just became a partner in a new company and I work for him. I make roughly $100 an hour but I don't work very much. My job even includes driving back all kinds of Jags, Porches, Mercedes and the like back to this area!!! So, I'll post again when I get MY info on how I like the TC.... Have fun CJ and hope to hear about the TC soon.... KEEP POSTING<br><br>Justin<br>Platinum 2G GS4
