Description
With our very own Ninja 400 race bike and a shelf full of trophies, it's clear that all of the hard work that our team put into hardware and tune development paid off! They poured hundreds of hours into our dyno and countless laps around tracks across the entire U.S., resulting in us winning the ASRA Moto3 National Championship on our Ninja 400 race bike. We used all of that racing data to develop this TST WORX Stage 2 ECU Tune, ensuring that it's able to deliver power gains you can feel across the entire rev range. It's designed to be installed on bikes equipped with an aftermarket full system exhaust, MWR Race Air Filter, and our TST WORX V2 Velocity Stacks, optimizing the additional airflow within the engine to reliably produce smooth and noticable power gains. If you're trying to pull away from the pack, this tune gives you the boost you're looking for!
EQUIPMENT REQUIREMENT: This tune MUST be paired with the TST WORX V2 Velocity Stacks, MWR Air Filter, TST Emission Block Off Kit, and an aftermarket full system exhaust. Failure to do so will result in poor performance that may fall out of the safe zone of operation.
NORTH AMERICAN MARKET ONLY: Please keep in mind that this is only available for North American market Ninja 400 motorcycles ONLY. All orders placed outside of the North American region will be canceled.
Premium 91-93 octane fuel is required for expected results and safety against knock.
Please note that if your "Check Engine" light is on previous to an ECU tune, the light will remain on after the reflash and must be cleared manually.

Q: Why is this tuned for specific parts? A: Each part upgrade adds new variables, and we developed this tune to optimize the airflow provided by our TST WORX V2 Velocity Stacks, the MWR Air Filter, and an aftermarket exhaust. Pairing this tune with different or substitued parts may not deliver expected results and may even hurt your motor.
