AA Custom Tuned Power Vision for 2015-Up RZR 900 S, Trail, XC

The Aftermarket Assassins Custom Tuned Power Vision is a Dynojet Power Vision tuner loaded with AA tunes for the 2015 and newer Polaris RZR 900 S, Trail and XC. It breaks the factory throttle limits that keep this motor detuned all the way to redline.

Why it holds up

• Throttle by wire limiters disabled for 100% throttle
• AA timing curve set up for 91 octane with a strong mid range punch and better top end power
• Fuel tables built for this motor to match the timing curve at 100% throttle
• Speed limiter removed in low and high gears. Most riders see 7 to 10 MPH of actual top speed gain.
• Rev limit set at 8800 RPM and fan on/off temps lowered to 190/185 degrees F

Fits

• 2015 and newer Polaris RZR 900 S, Trail and XC models
• Does not fit 2011 to 2014 RZR XP 900 models

In the box

• Dynojet Power Vision tuner loaded with AA custom tunes for this machine

Good to know

• Level 1: designed for the stock exhaust. A slip on works with it, but Level 2 picks up a little more with a slip on or full exhaust.
• Level 2: same as Level 1 with increased fueling for a slip on or full exhaust system.
• Level 4: modified fuel and timing maps for a big bore engine. Bore size and any other power mods are needed to build this tune.
• An optional kid mode tune limits the machine to 35% throttle and 35 MPH, and can be customized.
• Custom race fuel tunes are available on request.
• Horsepower gains on this motor vary with temperature and altitude. Average gains for low altitude riding in 50 to 70 degree weather are around 15 HP.
• Seatbelt limiter disabled and 2 foot limiters disabled (gas and brake at the same time).
• Reads and erases most trouble codes and data logs 25 parameters with one push of a button for review on a Windows computer.
• 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.
