Its about 300 or so for the tuner itself. Then its normally around 50 bucks per mail order tune. However, you would be getting a dyno tune, which means the tune will be specifically designed for your car. You will also get a dyno printout that shows your horsepower and torque curves. The horsepower estimate is fairly accurate, if not on the high side, however you will be needing to use a high octane fuel (93) after he tunes it so he can adjust the timing for more power. If you gain 30 horses, and for 600 bucks, thats 20 dollars a horsepower, so its up to you on whether or not you think its worth it. You can spend 600 on a CAI, headers, UDP, and exhaust and still not get 30 hp out of them. A good tune is one of the best things you can do for your
stang.
