The RIPP, Magnuson and Prodigy kits are all intended to be complete packages, ready to drive with the included tune. ProCharger gives the option of a "complete kit", or a "tuner kit" that does not include fuel injectors or the pre-programmed tuner. I know there's forced induction kits out there for other popularly modded cars that are incomplete or customizable that only include a "base tune" intended to let you start the engine and possibly limp carefully a short distance to a tuning shop. Because of this, some people are of the mind that you MUST get ALL forced induction kits custom tuned before driving the vehicle.

I've seen RIPP mention that they had some problems with tuning for higher elevations that caused some people to require local custom tuning. The bugs should eventually be worked out of the supplied tune for all of these kits such that no one should need custom tuning.
