2011-14 RZR XP 900 AA Custom Tunes for Power Vision CX, 3 & 4

Aftermarket Assassins custom tunes for the 2011 to 2014 Polaris RZR XP 900, built for the Power Vision CX, 3 or 4 you already own. The factory timing map is heavily detuned on the XP 900, and these tunes correct it along with the lean spots in the fuel map.

Why it holds up

• Much quicker throttle response and power delivery
• AA timing curve set up for 91 octane for more mid range punch and top end power
• Fuel curve corrected where the factory map runs lean
• Fan on and off temps lowered to 185 and 180 degrees Fahrenheit
• Rev limit raised from the stock 8400 to 9000 RPM

Fits

• 2011 to 2014 Polaris RZR XP 900

In the box

• AA custom tune files for your Power Vision, sent by email. No hardware ships with this order.

Good to know

• Best peak power is at 8000 to 8200 RPM at wide open throttle, around 55 MPH.
• Level 1: for a bone stock RZR XP 900. Average 5 to 6 HP gain on pump gas.
• Level 2: stock exhaust with a high flow intake. 8 to 10 RWHP gains with tune and intake.
• Level 3: aftermarket slip on or full exhaust with a high flow intake. 12 to 15 RWHP gains with tune, intake and exhaust.
• Level 4: big bore motor, aftermarket exhaust and high flow intake. Potential gains of 20 to 25 RWHP depending on the motor work. Big bore tuning may require customization and the Dynojet wideband module to log air fuel ratios.
• AA recommends its Recoil clutch kits to put the added power to the ground and reach proper peak RPM.
• This is a tune file for a Power Vision device you already own.
• After purchase, the store contacts you by email to collect your vehicle and Power Vision device information, then sends the tune files by email.
• Tuning a second vehicle with a PV4 requires an additional vehicle license, purchased through the Power Vision app.
• Tunes are final sale.
