I just bought a 1990 MMC 550CC with a Supercharger. This is the only mini truck I have ever driven so I'm not sure how or even IF the supercharger is working. Is there anyway to tell for sure? I searched the site but couldn't come up with anything on superchargers on a Mitsubishi MMC. I did see a couple post about other brands of trucks that say they have a supercharger light that comes on when under power but my MMC has no supercharger dashlight. Any Info on how to tell if it is working? Also, how do these 550cc with superchargers compare to the 660cc engines w/out superchargers????
