Polaris RZR Pro S ECU Bench Power Flash (SEND-IN ECU)
DESCRIPTION Refinements never end at Evolution Powersports. After achieving huge power gains and overall performance enhancements for the 181-horsepower Polaris twin that first debuted in the Pro XP platform, the new Polaris RZR Pro S opened the door for the wizards at EVP to further refine the already potent tuning packages. After months in the Dyno Lab and testing in the field, we're excited to re-release our all-new Pro S performance tuning upgrades featuring major enhancements across the board. Power delivery has never been better with crisp, head-pinning acceleration off the line to drastically improve 0-60 mph times, going from 5.63 seconds stock to 3.94 seconds on our Stage 5-X85 tune. Additional horsepower gains have also been realized throughout the Stock and Big Injector tune stages for an overall transformation that you're guaranteed to notice on the first pull. RECOMMENDED UPGRADES: It is highly recommended that you upgrade to EVP Silicone Charge Tubes and V-Flow Intake, as the plastic OEM units are highly susceptible to blowouts (SEE PHOTOS). Additional recommended components include BOV or BRV, high-flow exhaust, clutch kit and spark plugs.
