The Aftermarket Assassins Stage 2 Upgrade Kit turns the 2023 and newer 135 HP non intercooled Can-Am Maverick X3 into a 220 plus HP machine. It adds an intercooler, wastegate, clutching, full exhaust and AA tuning through the HP Tuners MPVI3.

Why it holds up

  • Three levels of performance on the intercooler and stock fuel pump setup, up to 250 HP
  • AA 3 inch full exhaust gains 4 to 7 RWHP depending on tune and cuts power fade on long pulls
  • AA tunes built on years of X3 ECU R&D carried over to the 135 HP MG1 platform
  • Throttle by wire set per drive mode and gear: snappy in sport, still smooth for crawling and loading

Fits

  • 2023 and newer Can-Am Maverick X3 135 HP base, non intercooled

In the box

  • HP Tuners MPVI3 with ECU unlock (performed at HP Tuners in Illinois)
  • OBDII to Can-Am diagnostic port cable, credits to flash the ECU, one AA custom tune
  • Black intercooler with fan
  • AA wastegate (7 to 18 PSI kit), BOV, charge tube and clamps
  • S2 clutch kit, catch can and full exhaust

Good to know

  • The OEM shroud over the intercooler is not used. The intercooler is oversized and needs slight trimming to drop into the housing.
  • The ECU must be sent to HP Tuners to be unlocked unless an unlocked ECU is purchased outright or exchanged. After the unlock, the ECU can be flashed any time.
  • Standard unlock averages 10 to 15 business days. Instructions to ship the ECU to HP Tuners arrive within 1 business day of purchase, and the buyer ships it. HP Tuners takes 5 to 10 business days, then returns it by ground.
  • Express unlock averages 5 to 10 business days, continental US 48 states only, using a UPS Next Day Air label.
  • A purchased or exchanged unlocked ECU arrives blank and needs BRP Can-Am BUDS2 software or a willing dealer to program it to the vehicle.
  • Insure the ECU when shipping it. AA is not responsible for shipping delays or lost ECUs.
  • A Windows laptop and basic computer skills are needed to flash.
  • The device flashes the ECU, data logs and reads and clears trouble codes.
