The "Tuner Kit" just means that this kit will not come with the ProCharger Branded Tune and fuel injectors. However, we have fuel injector options that you can choose from and MPT Custom tunes that you can choose from. If you purchase MPT tunes and our recommended FIC Injectors then you will have everything that wuld come with the regular ProCharger kit. Data Logging is required with ProCharger tunes, Dyno tuning is optional.
