The 2024 - 2026 Polaris RZR XP & XP4 1000 Engine Tuning by PPEI is engineered to strip away the limitations holding your machine back, delivering a seamless, high-adrenaline driving experience. Trusted as the number one choice for top racers, this custom tuning calibration transforms your RZR from a factory-tamed trail rider into an unrestricted off-road dominator.

Whether you are navigating technical rock crawls, tearing across the dunes, or dominating the track, PPEI’s expert tuning ensures your RZR responds exactly how you want, when you want.

The PPEI Advantage: Engineered for Dominance

We do not just add power; we optimize the entire driving experience. Here is what you gain when you flash your ECU with PPEI:

  • Optimized Fueling & Ignition Timing — Precisely adjusted through meticulous chassis dyno testing for optimal power output, a broader torque curve, and sharper throttle response.
  • Increased Rev & Speed Limiters — Boosted top speed and RPM limits let you stretch every gear to its maximum potential for thrilling, high-performance rides.
  • Lowered Fan Temperatures — Enhanced cooling efficiency keeps your engine in its optimal thermal range, preventing heat soak and maintaining consistent power in demanding conditions.
  • Removed Brake Torque Management — Enables aggressive, rally-style two-foot driving so you can power through corners without losing momentum.
  • Start in Any Gear — Fire up and go instantly without shifting into park or neutral, for greater flexibility and convenience.
  • Removed Seat Belt Limiter — Eliminates restrictions for a seamless, uninterrupted driving experience.

Proven Power: Chassis Dyno Verified

We back our claims with hard data. As shown in our chassis dyno testing, the PPEI tune delivers a noticeable, consistent power increase across the entire RPM range. While the stock calibration peaks at roughly 95.1 HP at the wheels, the PPEI tune pushes output to over 99.3 HP. More importantly, the tune fills in the mid-range dips and carries that power all the way to the newly raised redline, giving you more power exactly where you need it most.
