Aftermarket Assassins custom tunes for the HP Tuners platform on the Polaris RZR Pro XP, Turbo R and Pro S with the OEM stock turbo. These are tune files for riders who already own an HP Tuners RTD or MPVI device.

Why it holds up

  • Big horsepower gains depending on the tune level, with quicker throttle response and power delivery
  • Throttle by wire limiters, seat belt limiter and speed limiter in low and high gear removed
  • More throttle percentage and boost in low gear and reverse, with rev limit set at 9300 RPM
  • Fan turns on at 185 degrees F (stock is 190) and ramps up quicker to keep the motor cool
  • For reference, AA dynos a stock machine at 156 to 158 RWHP

Fits

  • 2020 to 2026 Polaris RZR Pro XP, including Dynamix models
  • 2022 to 2026 Polaris RZR Turbo R and Pro S, including Dynamix models
  • OEM stock turbo only. Modified or larger aftermarket turbos need the AA big turbo tunes.

Good to know

  • Requires an HP Tuners RTD, MPVI2, MPVI3 or MPVI4 you already own, plus the Polaris adapter cable
  • Flashing through the TDN phone app or the VCM Editor (laptop, MPVI2/3/4 only) uses 2 credits. Devices not purchased through AA get credits from the HP Tuners website.
  • Level 1 (91 to 93 octane): modified stock power tune with better boost maps, factory max boost of 16.5 to 17 PSI. No wastegate adjustment.
  • Level 2 (91 to 93 octane): 17.5 to 18 PSI and a 10 to 12 RWHP gain. Works on a stock RZR in most cases. No wastegate adjustment.
  • Level 3 (91 to 93 octane): 18.5 to 19 PSI and a 20 to 25 RWHP gain. Requires pre airbox intake tube (2020 models), exhaust, billet BOV and S3 clutch kit. A charge tube is suggested.
  • Level 3.5 (93 octane minimum): 19.5 to 20 PSI and 30 to 35 RWHP gain. Adds a charge tube to the Level 3 requirements.
  • Level 4 (98 to 100 octane): 197 to 200 RWHP on the AA dyno, 23 to 24 PSI peak. Same required mods as Level 3.5. Leaded fuels used consistently can shorten O2 sensor life.
  • Levels 5 and 6 require AA 1200cc injectors and a wastegate rod adjustment. Level 5 is built for 108 to 110 octane and made 210 RWHP on the AA dyno.
