AA Custom Tuned Power Vision for 2011-14-Up RZR XP 900

The Aftermarket Assassins Custom Tuned Power Vision is a Dynojet Power Vision tuner loaded with AA tunes for the 2011 to 2014 Polaris RZR XP 900. It fixes the detuned factory timing map and the lean spots in the stock fuel map.

Why it holds up

• AA timing curve built for the fuel tune you choose
• Fuel curve that adds low end and all around power where the factory map runs lean
• Rev limit raised to 9000 RPM (stock is 8400 RPM)
• Fan on/off temp lowered to 185/180 degrees F and seatbelt limiter disabled
• Best peak power when tuned is 8000 to 8200 RPM at wide open throttle, around 55 MPH

Fits

• 2011 to 2014 Polaris RZR XP 900 models
• Does not fit 2015 and newer RZR 900 models

In the box

• Dynojet Power Vision tuner loaded with AA custom tunes for this machine
• Dual lock Velcro for mounting

Good to know

• Level 1: developed for a bone stock RZR XP 900. Average gain of 5 to 6 HP on pump gas with strong low end grunt.
• Level 2: stock exhaust with a high flow intake. Same as Level 1 with more fuel for the intake. Tune and intake together can see 8 to 10 RWHP gains.
• Level 3: aftermarket slip on or full exhaust with a high flow intake. Tune, intake and exhaust together can see 12 to 15 RWHP gains.
• Level 4: big bore motor, aftermarket exhaust and high flow intake, with more fuel and timing. Potential gains of 20 to 25 RWHP over stock depending on motor work. Big bore tuning may need customization and the Dynojet wideband module to view and log air/fuel ratios.
• Reads and erases most trouble codes and data logs 25 parameters with one push of a button for review on a Windows computer.
• No need to send in your ECU.
• AA recommends its Recoil clutch kits to put the added power to the ground and reach proper peak RPM.
• Ships in 24 to 48 hours, since each tuner is custom programmed.
