So i've been keeping up with @Chrismnj 's thread and have been thinking about a supercharger for my 2500 which has the L96 6.0L. When Justin was tuning my truck we were having an issue with some knocking at WOT and we couldn't get rid of it; tried different gas stations, adjusted the tune, seafoam in case of carbon buildup, etc... just would't go away. I'm not a WOT kind of driver, the trucks for towing not racing, so I think he advanced the timing and we let it be (@BlackBearPerf can correct me if i'm wrong). So fast forward to the supercharger research, I came across a thread at silveradosierra where a member was asking about supercharging an L96, and a member replied with: Soooo insert cold feet... Would appreciate some advice/experience. I know of at least one FB group member who has a supercharger, might be the LY6 engine though (not sure if the ECM mentioned above applies). But even still, would the issue I had with knocking at WOT be an issue if I wanted to go with a supercharger/cam/etc upgrade?
