A SC does put put stress on a motor. Most motors can handle mild amounts of boost with any issues. I totally agree with the above and have the system checked. There have been a couple SC makes for the Jeep including Kenne Bell but getting the fuel curves and computer tuning right has been an issue. A speed density system which we have as opposed to a mass air system does not adapt as well to adding on forced induction.
