Are you using tires other than the stock sizes? Depending on your tire sizes, that could easily cause the TCS light to come on.
Also, this is the wrong forum for your post. This topic belongs in either "Technical and DIY" or "General Discussion". The "NSXprime Discussion" forum is for topics about the NSXprime website, not about the car.
