When I bought my car the guy said it had a shift kit and I thought it did but now that I have read some posts I don't think it does. The car will almost never chirp 2nd gear. And when I changed tuners it just shifted like a normal car untill I turned up the firmness. Do you guys think it really has one or was he just trying to make some more money. If it doesnt have one what kind should I buy and could I put it in my self or should a shop do it.
