They usually have a canned tune within the tuner but it's really not that great(compared to a dyno tune) Unless you know how to use it, you can adjust the fuel, timing, rev and shift points to get some performance out of the car but it won't be great. Get a dyno tune though if possible. That is where your going to get the most power, you can achieve big gains from them.
