Tune
ECU flash or piggyback fueling — the unlock for everything upstream of the throttle. Mail-in services remap your stock ECU, DIY kits let you flash at home, and a piggyback bends fueling without opening the ECU at all. Air filters ride along here.
The decision
A mail-in flash (~$250) is the most result per dollar in all of modding: fueling, throttle restrictions, top-speed limiters, often quickshifter and autoblipper enablement. Go DIY kit if you'll iterate maps or tune more than one bike. Go piggyback only if your ECU is locked or your dyno shop insists.
