Ok Im throwing this out there in hopes of some help with my gen 3. It has the Novi 2000 supercharger along with the BB exhaust. Just today out of the blue it doesnt have the power that it did. When I let off the gas while it always had that crackling backfire, it is now very excessive. Burnt rubber smell in the cabin when the engine is turned off. Idles fine and all gauges are fine. Its almost as if the supercharger is not kicking in. It definitely doesnt have the throw back power it normally does. Today in first gear it was slow to move with a lot of gas. Any ideas would be appreciated.
