My g60 has been sitting in my driveway for about 6 months covered but its been really cold and snowing some days and raining also. I just started it today after 6 months and let it warm up and took it out for a drive the problem is that i lost boost im running 6-7 pounds and before i was running 10 pounds of boost so i was wondering if anybody can help me on what it could be, my supercharger was built like 9 months ago and its not leaking oil anywhere so can anybody tell me what it could be ???????
