Description
Upgrading 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.
AFTER TUNE: Please be aware that a temporary Check Engine Light will appear and the Mode button will be temporarily disabled after reinstalling your flashed ECU. These issues will clear after two or three ride cycles and the dash will return to normal.</p>

Work good, nice and bright, just make the plastics covers for the connectors longer. Idk if that’s standard, but I had to put more on cause they where shorting. You can also just use a tiny peice of electrical tape tho
