I sold my car and just selling some the parts I didn't use on the car. As far as it better or not, It would be best to read and see what people say. At the time when I bought it people said it was better and I went that way.
I'm turbo and didn't run it until the turbo was put on at the same time. Substantial gains up top, leaves something to be desired down low but I think that's mostly my tune. And it looks badass!
