Aftermarket Assassins ’17-’20 Polaris RZR XP Turbo Stage 3 Lock & Load Kit

• Kit Includes: AA Tuned PV3 Tuner, S3 Clutch Kit, Snap Ring Delete Kit, BOV, Slip-On Exhaust, Pre-Gapped Iridium Spark Plugs, Charge Tube, Intake Tube
• The ultimate Lock & Load! This Stage 3 kit is the most complete bolt-on kit you’ll find for your RZR XP Turbo. This kit combines absolutely everything you need to take your RZR to the next level. It includes tuning, S3 complete clutching, our billet blow off valve, secondary clutch snap ring delete kit, pre-gapped iridium spark plugs, performance slip-on exhaust, high flow intake tube, and high flow charge tube. Our custom tuned Powervision ECU flash device will send the tunes directly to your ECU, allow you to change tunes within 5 minutes, and easily return to stock. It also has data logging capabilities, diagnostics, and is a great gauge where you can read boost, throttle, RPM, and more. We then transfer the power to the ground Much better than the factory with our S3 complete clutch kit. Though we test mostly in the real world to get the best results, we did see a 7-10 HP increase from 20 MPH to 40 MPH on the wheel dyno with just the clutch kit. This kit also includes our high flow exhaust to get rid of the catalytic converter, and restrictive stock muffler. This allows heat to escape much quicker, and allows us to tune higher. Our exhaust features an Excellunt sound that is fully adjustable with our quiet core that blocks off one outlet. The blow off valve is an o-ringless tip design and is needed when increasing boost pressure to prevent factory valve failure. It also comes with a plug so you can have that classic blow off CHHHH sound when you want it. Our high flow intake and charge tube help to lower intake temps going into your motor which is Huge when going with our level 3 or higher tunes. For more detail on each product, see the individual listings.
• Massive horsepower gains bundled into a simple package
• Quicker throttle response and power delivery
• All level tunes feature: Throttle by wire limiters disabled, less sensitive overboost code, Fan on/off temp lowered to 185 degrees Fahrenheit, Seatbelt limiter disabled, Speed limiter removed in low and high gears, Rev limit at a safe 9200 RPM, more throttle in low gear, better throttle response, and much more!
• ECU Type/O2 Color drop down choice: 2017-18 models ALL have the standard black lead. In 2019+ models blue O2 leads are wideband models and we must know this. These models are a different ECU type and will NOT do an ECU read (we supply your stock file). For more information on this, see this link: /tech-blog/f/rzr-turbo-evap-ca-models#
• 1 tune is included in the price. We would recommend going with 2 tunes, especially if you choose level 3 or higher.
• For reference; a 2017-Up 168 HP crank horsepower stock machine will dyno at 135-138 RWHP on our dyno
• All tunes level 3 and higher will need the waste gate rod shorter for maximum power. Click Here for a link on how to easily adjust the waste gate.
• Level 1: This tune is a modified stock power level tune, but has better boost maps to help keep you in the power. We disable many limiters, up the speed limit, rev limit, and make necessary fuel & timing changes. The factory tune runs a max of 14.5-15 PSI of boost, and we keep that in this tune, it’s just easier to obtain & maintain that level.
• Level 2: This tune offers 16-16.5 PSI of boost and a 10-12 RWHP gain. This tune can be used with the stock or aftermarket exhaust. Clutching is not needed, but is highly recommended with this tune, as just tuning the machine will not properly transfer the power to the ground. Clutching is another big horsepower gain. 91 Octane tune.
• Level 3: This tune is a game changer! Hitting hard at +20-25 RWHP, this tune offers the highest boost possible (17-17.5 PSI max) on 91-93 octane fuel. Due to the thicker head gasket and larger injectors on the 2017+ models, we are able to get away with his kind of power on pump fuel. These are absolutely huge power gains that will have you grinning from ear to ear. This tune must be used with an aftermarket exhaust and requires clutching. 91 non ethanol/non oxygenated fuel, or 93 octane is required. If fuel in your area is poor, we’d suggest using a half can of VP Madditive or Boostane to help fuel quality. 1/2 gallon of 110 or better race fuel would also work to boost octane levels. Waste gate rod adjustment (2 turns shorter) is needed for tune to work correctly. Billet BOV is also highly recommended.
• Level 4: This tune is designed for 98-100 octane (will run on UTV 96, or most fuels up to 110 octane) and was developed using one can of VP Octanium to a tank of fuel. Mixing other race fuel with the tune to get 100 octane output would work great, just keep in mind leaded fuels can take out o2 sensors when running leaded fuel consistently. From extensive testing, we know that this is the limit of the factory turbo before it becomes inefficient and simply starts blowing too much hot air. We correct many maps for this octane rating, assuring the most possible power. This tune pack a huge punch with just a small amount more octane. Exhaust and clutching are needed with this tune. Waste gate rod adjustment (2 turns shorter) is needed for tune to work correctly. Billet BOV is also recommended.
• Level 5: Get ready to drop the hammer! If you don’t like to lose races, this tune is your friend…. and If you’re friends don’t like to lose either… they might not be your friends for long. This tune is developed for 110 octane fuel (unleaded is recommended if you plan on keeping your O2 sensor) and really hits hard. This tune runs around 18.5-19 max PSI. This is where we found the turbo to max out for the most part, so we went to our timing tables and did some work. Adding a revised timing curve with these boost pressures is a recipe for absolutely stupid power that hits harder than you can imagine. Exhaust and clutching are needed with this tune. Waste gate rod adjustment (2 turns shorter) is needed for tune to work correctly. Billet BOV is also recommended.
• Level 6: Have E-85 fuel local to you? Time to fill up and start turning heads! This tune is developed on the stock injectors and stock fuel pump for E-85 fuel… that’s right, just gas up and hammer down. E-85 is a great race fuel replacement as it runs very cool and can sustain high boost and advanced timing maps….. which equal awesome power! We crank out all our Level 5 tune has and even a little more. Keep in mind E-85 takes about 30% more fuel to run, so it will guzzle fuel fast. This tune runs an average of 18.5-19 PSI of boost. Waste gate rod adjustment (2 turns shorter) is needed for tune to work correctly.
• How to tell if you have a EVAP model: /tech-blog/f/rzr-turbo-evap-ca-models
• Why our tunes over the DynoJet tunes? This really depends on our tune level. The great thing with our tunes is they are easily labeled, list boost numbers, and rough horsepower gains. They have been proven to make and hold power longer than the DynoJet tunes. Not only this, but we test with clutching, exhaust, and other parts to ensure our tunes work well with all factors. Lower level tunes (1-2) are actually much safer than a DynoJet “max boost” tune especially if running stock exhaust, yet deliver more power than their low boost tunes. Safer tunes will hold power longer, and be much easier on your motor. When your RZR de-tunes because boost is too high for the modifications or fuel, it can become slower than stock! Our Level 3 tune has higher boost, and comes on harder. Our Level 4 and higher tunes are adding in race fuel and will offer even more power than any DynoJet tune. Since we have so much time on RZRs, we know the limits and can push the limiters further giving you higher speed limits, and many other things hidden in our maps. Everything is taken care of for you, ensuring you have the best tune(s) out there… that should be worth every penny!
• Please see helix options below:
• Torsion Anti-Chatter Kit: Upgrades to a complete secondary converted to a Torsion style spring and helix. The main benefit is better belt grip with the Torsion spring that gains rate as it shifts. Constant pressure against the helix buttons for less annoying secondary clutch chatter which also extends the life of the buttons. You’ll also notice smoother engagement which is excellent for those crawling. Secondary bushing comes peened over to prevent walking out. The Torsion kit slightly limits top speed and should be used with the AA primary clutch limiter. 80-85 MPH top speed for most models.
• Performance Helix 1031/Torsion 1026 (aggressive holeshot): For 2 seat XPT 28-32″ Tires / 28-32″ paddles. For 2 Seat Turbo S running 30-33″ Tires or Paddles. This helix works excellent for the listed setups and has a more aggressive shift angle from 0-25 MPH over the 1024 performance helix. This is best for holeshots and aggressive riders that are trail riding, dune riding racing, and drag racing. This setup will still crawl good when needed, but if your riding style is more slow speed/crawling, we’d suggest the 1024 helix or 1032 Torsion helix.
• Performance Helix 1024: For 2 or 4 seat XPT 28-32″ Tires or paddles. For Turbo S 2 or 4 Seat with 30-33″ tires or 30-32″ paddles. The only difference over the 1031 performance helix is the shift angle from 0-25 MPH is slightly less aggressive. This makes it better for crawling and those slow speed situations, but it still pulls like crazy when needing to accelerate hard. Keep in mind if you have a 2018+ 4-seat model they are geared higher. If your tires or paddles are 31-32″ and heavy, you may want to go with the high load clutch kit
• High Load Helix 1021/Torsion 1032: For 2 seat XPT 34-35″ Tires. For 4 seat XPT 32-35″ tires / 32″ paddles. For 2 or 4 seat Turbo S running 34-35″ tires. If you are using very large/heavy tires, the high load helix might be the choice for you. The high load helix is recommended for those turning heavy 34-35″ tires. This angle slows the shift down to help act like it’s “gearing down” the secondary clutch. This helps prevent over shift and belt slip. Keep in mind if you have a 2018+ 4 seat model they are geared higher. If your tires or paddles are 31-32″ and heavy, you may want to go with the high load clutch kit
