    Gladius Power Commander V

    Adds instant power and is super simple to upload maps from my laptop. I paid 119.99 for it :)

    Used on a KLR650. Power increase was nominal but fuel efficiency was increased and helped eliminate "popping" with my aftermarket Vance and Hines exhaust. Very user friendly with easy to follow instructions. You dont have to completely remove the carb for this upgrade but you really should so it can be properly cleaned at the same time.

    Cobra FI2000

    Did the stage 1 upgrade on my 2007 Night Rod Special which consisted of exhaust, hi-flo air filter and fuel manager. Installation was a bit challenging considering the front and rear fuel injector connections are directly in between the jugs. A set needle nose pliers will speed up the process. Factory settings from Cobra are preset at 2-2-2. Still ran lean so I bumped all 3 pots to 4-4-4. No more lean condition, bike runs/performs fine. Decent product!

    fjr1300 Powsr Commanded

    I bought the Power Commander to make my 2005 FJR1300 run cooler; and it did. The bike was running so lean that I couldn‘t ride in the summer because the fuel tank was so hot. The tank remains cool now after a ride. The price I paid was the lowest I found.

    Vance& Hines Fuel Pack

    Throttle response is like night and day from stock. I really enjoyed the performance it gave my bike. Excellent products would definitely recommend to a friend. Installation was extremely easy in my 2006 Softail Heritage.
