That's where our TST WORX engineers step in. Using our in-house dyno, we've developed a custom ECU bench flash that optimizes engine performance and delivers substantial power gains throughout the RPM range. How substantial? We're talking over a 34% increase in top-end power, more than 8% additional power in the midrange, and a 4% boost in peak horsepower compared to a Z900 equipped with an aftermarket exhaust and stock ECU tune. The result is a more responsive, powerful machine that delivers the performance you want, whether you're carving through corners or opening up the throttle on the straights. Unleash the true potential of your Kawasaki Z900 with a TST WORX Performance ECU Tune and experience the difference for yourself!\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"color: #f00;\"\u003eAFTER TUNE: \u003c\/span\u003e\u003c\/strong\u003ePlease be aware that the Check Engine Light will be on and the Riding Mode and KTRC will flash after reinstalling the ECU.
