The tensioner has been replaced and wow........it's like a whole new car. The power is great, it shifts a lot better. THIS is what I was expecting from the supercharger. So maybe my tensioner was failing that whole time and wasn't really keeping tension. The SC'er is a lot more vocal now as well. Although, there is a drill/whistle type sound in the beginning that makes me think there may be another bad gasket somewhere..........maybe the aroundt he header and the donut need replacin.
