    The DH Motoring Stage 3 Package includes the following:

    • DHM 13.4:1 High Compression Piston
    • DHM Stage 3 ECU Flash
    • Camshaft
    • NGK CR9E Spark Plug
    • Spark Plug Spacer

    Combined with your aftermarket intake and exhaust, this is the most you can get out of your Grom / Monkey without doing any head work. After dyno testing we were repeatedly seeing 13.5hp at the wheels (SAE) run after run! The Stage 3 package makes more power than a stock Grom at every RPM and double the horsepower at 9000+ rpm! 91 octane fuel is absolutely required. Any fuel with a lower octane rating may result in engine damage!

    *This is a drop ship service and requires ECU to be mailed in for flashing services
