  1. YFZ450 & YFZ450R General Talk
    I have a 2013 se and i am considering to buy a full hmf exhaust. I know i need a tuner, but i has got told the only good one is a vortex and i are not giving 700 for that. I found out you could get the ecu reflashed. Does a reflash work and will it work like a controller/powercommander?

    I’m doing a couple upgrades, intake/full exhaust. What are the pros and cons of the ECU flash? I ride MX but don’t race just want my bike to run correct as to not blow the engine, can a flash tune it without a dyno? Any info will help.
