Like Boiler said, it is in fact a tune, it's just not specific for your car. It is specific for the engine. You can always have an authorized dealer do a dyno tune but, again as Boiler said, I don't think you'd get a much different result. The tune (and I hope someone will correct me if I'm wrong) doesn't take into account that you might have a CAI or bigger TB but the difference in tuning would be negligible.
