This simple kit is the best way to wake your Pro R as it comes with our proven ECU flash. The ECU flash adds some amazing horsepower from low end to high end RPM and really gives your machine that \"snap\" you're looking for. Our AA Stage 3 clutch kit compliments the tuning perfectly by more efficiently transferring power to the wheels and ridding yourself of the very lazy factory clutching setup and poor belt grip. We finish out the kit with our AA RZR Pro-R full exhaust (head pipe and muffler) and it's just what your machine needs! We set out to produce an exhaust that looks great, sounds great and has adjustable sound levels while producing the most power possible.\u003c\/p\u003e\n\u003cp\u003eCenter exit exhaust with a chambered muffler: This design uses your OEM tip\/spark arrestor making it a very quiet exhaust with the 3\" side dump closed with optional 3\" Stealth Quiet Core. Open up that 3\" side dump and let it scream when you want to! This center exit design with 3\" cutout allows for wild and mild sounds in seconds by bolting\/unbolting the 3\" Stealth Quiet Cap, or the flip of a switch if you choose to upgrade to the electronic cutout.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLooking for the best\/most badass ECU tuning available for your RZR Pro R?:\u003c\/strong\u003e AA's performance tunes are now available to gain horsepower and torque. Through our advanced ECU tuning we are able to modify parameters correctly to gain you the power needed. We are highly experienced in tuning RZRs and this will show. The Pro R uses a new Bosch MG1 ECU. Currently no programmers are available that flash without first having the ECU unlocked. The HP Tuners Remote Tuning Device (RTD) allows the ECU to be flashed remotely at any time using the AA\/HP Tuners RTD and your smartphone once the unlock process has been completed from AA.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHP Tuners Remote Tuning Device (RTD) option:\u003c\/strong\u003e Upgrades to HP Tuners RTD which includes the RTD, OBDII to Polaris Diagnostic Port cable, necessary credits to flash your ECU, one AA custom tune (more tunes optional), and ECU Unlock performed at the AA facility. Requires ECU to be sent in to be unlocked unless purchasing ECU outright . After the initial unlock, the ECU can now be flashed remotely at any time using the HP Tuners RTD and your smartphone. See links at bottom of product page for flashing your vehicle and data logging.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncluded Level 2 Tune\u003c\/strong\u003e: This tune is developed for a Pro-R with aftermarket exhaust on 91-93 octane. It has just a bit more timing and a bit more fuel over Level 1. This tune adds +16 RWHP peak and a massive +19 RWHP at 38 MPH (This is gaining roughly +25 crank horsepower) putting you at roughly 250 crank horsepower with just a flash and exhaust! Our included Stage 2 clutch kit with this tune really helps the belt to grip and to help drive the extra power to the wheels. **Note : If you already have cams or are planning on upgrading to cams, cams can be run with our Level 2 tune if you already have it. However, hot starts are an issue with these cams and the Level 2 tune. Our Level 3 tune is suggested with these cams as it fixes hot starting, has better low end, and slight peak RPM fueling adjustments. For Level 3\/cams We HIGHLY recommend upgrading to the HP Tuners RTD. While our tunes have been proven to work great with our shop vehicle and many others, some may have idle issues that need a revised tune. Higher lift camshafts are very finicky at idle. If you were to have idle issues, with the HP Tuners RTD we can deploy revised tunes quickly and easily whereas with a simple ECU flash that is not an option - you would need to send your ECU back for a reflash.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy AA tunes over others?:\u003c\/strong\u003e We have been tuning UTV's with CVT clutches for a long time, longer than almost anyone in our field going back to the 800 RZR. Tuning a CVT vehicle properly is not an easy task as you have so many variables at one time. We spend the time to wheel dyno(with actual UTV tires) correctly per modification, and have advanced ECU calibration and clutching knowledge to do so. Every change in horsepower can result in us changing clutching several times. We also develop most of our supporting mods so we know everything works correctly, and build parts to fit the vehicles needs. Lastly and honestly the most important; we then back up our results with real world data logging on local trails and our facility on 110 acres. It's this combination that truly makes the difference and why AA normally has a faster vehicle with the same or less rated tune horsepower. We left nothing on the table on the Pro R bolt-on parts, if others claim more power\/gains for the same mods use caution in believing it\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch5\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eBig horsepower gains depending on the level of tune\/modifications (see tune descriptions below for more details)\u003c\/li\u003e\n\u003cli\u003eMuch quicker throttle response and power delivery giving a whole new feel to the vehicle\u003c\/li\u003e\n\u003cli\u003eThrottle by wire limiters disabled\u003c\/li\u003e\n\u003cli\u003eFan on\/off at 185 degrees Fahrenheit (Stock is 190) which is just above the thermostat opening temp.
