AA Boost Control Box for 2021-Up Can Am X3 RR

The Aftermarket Assassins Boost Control Box adds boost and power to the 2021 and newer Can-Am Maverick X3 RR, with four tune levels you pick on the fly from a rotary switch.

Why it holds up

• Plug and play. Installs at the MAP sensors and battery power, and leaves no trace once removed
• Manipulates MAP sensor data to raise boost, increase spool and bring peak boost on quicker
• Air fuel ratios tested and verified at each tune level. The RR wideband ECU trims fuel to the requested ratio
• Factory safety parameters for the motor and turbocharger stay in place
• Return to stock with the switch in Stock mode or by unplugging the box

Fits

• 2021 and newer Can-Am Maverick X3 RR, 195 HP and 200 HP

In the box

• AA Boost Control Box
• Wire harness
• Rotary switch with AA tune levels 1, 2, 3 and 4

Good to know

• Stock X3 RR on the AA dyno: 178 to 180 RWHP on 32 inch tires at roughly 18 to 19 PSI.
• Level 1, 91 to 93 octane: 188 RWHP. Okay on a bone stock machine. Averages 19 to 20 PSI with the stock wastegate spring.
• Level 2, 91 to 93 octane: 193 RWHP. Peaks around 22 to 23 PSI. AA blow off valve kit recommended. Shorten the wastegate rod 2 turns from factory.
• Level 3, 91 to 93 octane: 204 RWHP. Peaks around 23 to 24 PSI. AA blow off valve kit highly recommended. Shorten the wastegate rod 4 turns from factory. For hard dune riding run 93 octane, add booster, or add an aftermarket exhaust.
• Level 4, 95 to 100 octane: 213 RWHP.
• The switch can be disconnected and the last position is saved.
• The box does not change pedal response or the reverse limiter. AA sells a separate Pedal Control Box and Reverse Override Switch for those.
