    yes, if you got the 185hp you need the gear upgrade kit to spin the charger faster.
    185@7650rpm with stock gears = approx 6 lbs boost
    185@7650rpm with 215 gear set = approx 7 lbs boost..

    and once you do the gear set you can upgrade to any of the "big boy" chargers later.. they all come with the 16 tooth 215 gear on them..

    add a 05 rxp/rxt ecu and fuel reg and you'll see 8100 RPM and allmost 8psi.
