Aftermarket Assassins '24+ Polaris RZR XP 1000 Stage 2 Lock & Load Kit w/ Dual Suppressor Exhaust
Lock and load your 2024+ Polaris RZR XP 1000 and get ready for some serious kick! The 2024+ RZR XP 1000 is a fun machine, but Polaris left room for improvement on the table. This simple kit is the best way to wake up your XP1K as it comes with our proven ECU flash. The ECU flash adds some amazing horsepower from low end to high end RPM and really gives your machine that "snap" you're looking for. Our AA Stage 3 clutch kit compliments the tuning perfectly by more efficiently transferring power to the wheels and ridding yourself of the very lazy factory clutching setup and poor belt grip. We finish out the kit with our AA dual suppressor slip-on exhaust and it's just what your machine needs! We set out to produce an exhaust that looks great, sounds great and has lower sound levels than stock. We designed this to be quiet and ended up making big horsepower gains as this motor LOVES the volume of this exhaust. We picked up 4rwhp over a single outlet muffler, and it carries out further.... you can really feel the low to top end pull which is massive over the stock exhaust, still offers big gains over our single muffler.
The 2024+ RZR XP 1000 uses a highly secure Bosch MG1 ECU. To use a programmer on this ECU, you must first send your ECU in for a specific unlock process (unique to that device). Besides our standard bench flash, we have two programmer options which are the AA/Dynojet MG1 PV3 or the AA/HP Tuners RTD.
Included Level 2 Tune: This tune is developed for an XP1K with aftermarket exhaust on 91-93 octane. It has just a bit more timing and a bit more fuel over Level 1. This tune adds +7 RWHP peak and a massive +9 RWHP at 30 MPH (This is gaining roughly +10-11 crank horsepower) putting you at roughly 125 crank horsepower with just a flash and exhaust! We would highly suggest our clutch kit with this tune to help with belt grip and to help drive the extra power to the wheels. Due to how these motors/tuning works, this tune should work with about any aftermarket exhaust, but was tested and designed with our AA slip-on exhaust.
Looking for race fuel tunes? We were also, but unfortunately we found no real power increase by adding octane. Certainly a little extra octane is never a bad thing to keep your ECU from pulling timing based on engine knock, but we tried various attempts to make more power with no significant results.
Evap (50 State/Cali model) or Non Evap (STD) Model: See the sticker located in your drivers side front wheel well as it will state which one you have. Your ECU should also have a label on it stating if it's an Evap, but we like to verify with the VIN sticker also as sometimes Polaris is not correct on the ECU sticker.
Features:
- Works with all models including ones with Dynamix and/or Evap models.
- Big horsepower gains depending on the level of tune/modifications (see tune descriptions below for more details)
- Much quicker throttle response and power delivery giving a whole new feel to the vehicle
- Throttle by wire limiters disabled
- Fan on/off at 185/180 degrees Fahrenheit (Stock is 205/192) which is just above the thermostat opening temp.
- Speed limiter removed in low and high gears
- Seatbelt Limiter Removed
- Start in Any Gear with Brake
- More throttle % in low gear and reverse as the factory limits these gears to not open the throttle fully
- Rev limit at a safe 9200 RPM (stock is 8800). Ideal peak RPM @ 55 MPH is 8400-8600 with the flash, but 9200 is for ramp up overshoot/top speed.
- AA's wicked timing curve is safe for the fuel octane recommended, but we do a much better job of finding timing limits for ramp up/more torque. Many others simply focus on wide open throttle timing/fueling. AA's tunes are developed for 91 octane unless specified otherwise.
- AA's modified fuel curve will still get decent mileage cruising, but is corrected over the factory lean AFR when needed most on higher throttle inputs.
- If you have any other needs in these tunes, or any concerns; please e-mail!
- Stage 3 Clutch Kit includes: Setup/Installation sheet, AA Recoil magnetic adjustable clutch weights, primary spring, primary limiter washer, secondary spring and AA helix. The initial setup guideline shows the best setups for dunes, mud, or all around trail riding. This also has brief instructions on installing your clutch kit among other important information.
Kit Includes:
- Requires ECU to be sent in for programming/unlocking unless choosing to purchase ECU outright
