Be careful if you get one of these damn things. My tires wont stop smoking. But it's so much fun to play with. I got it last week and I have been messing with it a lot and doing the tranny settings and using the cobra tune and I cant get any traction in 1st gear and they keep spinning into second. We got lazy and board at work today so we took my car into the parking lost and laid some rubber for a while. After reading up on it it's pretty easy to use and tweak. I just wanted to say it's the best mod for the money.
