I am very impressed. Car feels stronger and shifts MUCH better. Just what I expected. I haven't put very many miles on it since I got it back but right now I'm very happy!! I will post some more long term results after a few more miles and a mpg check. I would recommend them to anyone interested in a mail order tune!
