...gets worse with more speed? The super charger also does not seem to be doing anything unless it is trying to work at 80mph and vibrating alot...not really sure, but it feels like its a drive shaft or something in the drive train. Also i had a non SC previa from 94 and it has more get up n go....whats the deal? Anyone know about the superchargers and the all trac vibration issue above 80 mph? Definitely not a tire out of ballance as they are brand new and it is not like that problem i feel.
