Stage 1 Tune Features
This ECU reflash was tuned using premium 93 octane pump gasoline. 93 octane should always be used when operating with this tune. DescriptionUpgrading your 2026+ Yamaha YZF-R7 with a full system aftermarket exhaust is one of the best ways to enhance sound, style, and performance, but without proper ECU tuning, your R7 won’t be able to fully capitalize on those potential performance gains. That’s where the TST WORX Performance ECU Flash comes in. Instead of a one-size-fits-all map, we develop exhaust-specific tunes using real dyno testing to ensure optimal fueling, throttle response, and power delivery for each setup. Our tunes are designed to safely support the increased airflow of aftermarket systems while extracting maximum performance. Simply choose your exhaust from the dropdown menu and send in your ECU for flashing - it’s a straightforward process that helps you avoid performance loss and improper air-fuel ratios. Unlock the full potential of your R7 and experience the difference with a properly dialed ECU tune. NORTH AMERICAN MARKET ONLY: Please keep in mind that this is only available for North American market motorcycles ONLY. All orders placed outside of the North American region will be canceled. You are responsible for sending us an undamaged stock Yamaha YZF-R7 ECU. We will reflash the ECU and send it back to you ready to be reinstalled. Once an ECU is flashed, all sales are final and no refunds can be issued. TST ECU Tunes are shipped after we receive and flash your ECU.
