    check all pipes if there are any boost leak, try replacing plugs just in case

    Even though your supercharger is spinning in one direction, it could still be a weak clutch that is slipping at higher rpms.

    Any fault codes? Could be a boost leak, bad clutch, Misfire bad injector bad thrttle
    body

    does it pull hard to 6500 or struggle to get there?

    is the prop and housing in good condition?
