Good deal. I'm no tuner but I've tuned a number of cars with various setups. I can tell ya that I was never able to get the hang of the TwEECer. I ended up ditching the one that I had for something else. It's not to say that it's not a decent piece of equipment it's that it and I did NOT get along very well. There's some folks on here that do very well with them.
It's hard to learn how to tune --AND-- the TwEECer at the same time.
Find a dyno tuner if possible. You'll have more hair left on your head after. hehe
