No updates. Been daily driving the car w stock tune & supercharger belt disconnected. I won't know until the weather gets warm again if it's the supercharger or car that's problematic.
I've pretty much given up on the car at this point. A slew of other issues came up, so I've decided to trade the car in to the dealer. I can't in good conscience sell this to someone else.
I will be selling the supercharger for parts. The car also has decent snow tires mounted on m68s, clear euro lights, uuc ssk, & a remus catback exhaust.
If anyone wants to trade their ambers or stock exhaust, shoot me a pm.
