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 Turbo R 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 Turbo R and Pro XP 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.

TUNE FEATURES

• Massive wheel horsepower gains
• Speed limiters raised in high and low gear
• Rev limiters raised in high and low gear
• Torque limits raised for enhanced responsiveness
• Race Start/No-Brake Start – No need to press the brake to start vehicle
• Revised fan temperature settings significantly lower coolant temperatures
• Improved boost response and low-to-mid range power
• Left-foot braking enabled (gas and brake at the same time without going into limp mode)
• Fueling corrected so no additional controllers are required
• More aggressive throttle and overall throttle response
• Big Injector tunes include EVP 1300CC Injectors (set of 2), and EVP Wastegate Actuator

• STOCK INJECTOR NOTE: Stage 3-93 and Stage 3-96 requires the spark plugs be gapped to .018, or purchase EVP PRE-GAPPED PLUGS.

Dyno Testing / Tuning the PRO XP and Turbo R:

We baseline dyno tested the 181 crank HP PRO XP on our Dynojet chassis dyno at 148 - 150 WHP all stock which translates to about a 18% drivetrain loss.  We installed our EVP Performance ECU software calibration to improve overall power of the engine on pump 91 octane fuel and gained a tremendous power improvement over stock. The EVP software tune alone unlocked an additional ~13 whp from this 925CC Polaris Prostar engine on 91 octane fuel with stock exhaust.  Additionally, the cooling fans are triggered 15 degrees cooler, the rev limits and speed limits are raised and the ignition and fuel tables are calibrated for optimal power. Additional improvements are achieved with our exhaust upgrade and Stage 2 (91 Octane) software at ~176 WHP. Our Stage 3R (93 octane) delivers ~185 WHP.  

Development

EVP has spent many years developing software for the Polaris XPT platform with our fleet of company owned XPT’s (16 XPT, 17 XPT, 18 XPT “S, 19 XPT CALI)  to enhance the performance of this iconic vehicle.  Our continued R&D of this new PRO XP platform allows us to stay on the cutting edge with industry leading performance. 

When looking to purchase a tune for your $20,000+ vehicle, the first thing you should ask the tuning company is “do you own a PRO XP?”  Most companies do not own the vehicles they sell tunes for. They essentially “borrow” a vehicle for a few days to perform development.  At EVP, we believe that in order to perform proper R&D, the vehicle must be owned so the necessary development can be done both on the dyno and in real world conditions.  Our company owned XPT’s and new PRO XP have spent countless hours on the dyno to test different software calibrations and hardware components.  

Once the tuning was complete, our vehicles were field tested for months in Arizona, California, Colorado, Idaho, Michigan, Minnesota, Utah and Wisconsin. These places represent the vast majority of conditions our customers drive their vehicle and this helps to ensure the tuning is optimized and tested in the environment our customers ride.
