Aftermarket Assassins ’21+ Polaris RZR Pro XP/Turbo R/Pro S Stage 1 Lock & Load

• Note 2021-Up models have a different helix design and do not need the pre-airbox intake tube* Price difference for years reflects this.
• Lock & Load! This Stage 1 kit provides a big increase in horsepower and torque simplified into an easy package. Tuning and clutching on the Pro XP/Turbo R/Pro S go together like high powered rifles and tannerite. Together they pack a huge punch for the ultimate power gains to the wheels. The tuning allows for great power depending on the level tune, supporting mods & fuel you want to run. We change boost, timing and hundreds of parameters to deliver safe, yet big horsepower gains. The clutching then transfers that power and turns it into wheel power instead of simply just turning it into RPM. To make sure your airflow is not cut off, we also include our pre-airbox intake tube. This kit is normally/best paired with our Level 2 or 3 tune.
• 2021-Up Kit Includes: PV3 Tuner, S3 Clutch Kit, Butter Shift Washers, Clutch Limiter, Iridium Spark Plugs Pre-Gapped
• Clutch kit includes setup guideline that lets you know how to setup your weights for tire size & tune level (Works with 30″ – 35″ Tires, 30-33″ Paddles)
• If needing extra shims to align your clutch properly, we recommend our P90X Secondary Clutch Alignment Shim Kit.
• We highly suggest reading this article on the P90X clutch system to make your decision about clutching: /tech-blog/f/2020-rzr-pro-xp-clutch-issues#
• Optional to upgrade to our HD primary clutch. If upgrading to the HD primary clutch, you will need the P90X clutch puller to pull your OEM clutch.
• If sticking with the OEM primary clutch, we highly suggest the optional Revolver Tower Lock Cover
• Kit includes iridium spark plugs as the Pro XP models have had issues with low power/bad plugs. A fresh set of plugs, and longer lasting iridium plugs have been the cure.
• Quicker throttle response and power delivery
• Throttle by wire limiters disabled
• Fan on/off at 185 degrees Fahrenheit (Stock is 190). The fan also ramps up in power quicker to keep you running cool.
• Optional start in any gear! Does not need to be in park to start. Will start without brake but may throw a code. Press brake to start until we/DynoJet figure this issue out. Keep in mind this is removing a safety feature.
• Seat belt limiter disabled
• Speed limiter removed in low and high gears
• More throttle % and boost in low gear and reverse
• Rev limit at a safe 9300 RPM
• See how to install and use the tuner in this VIDEO
• No mess of having to send in your ECU & this device is a much safer way of programming. Simply plug in to your Diagnostic port, click tune, wait, and go ride!
• Very easy to use tuner that can also check and erase most trouble codes
• Easily data log 32 parameters with 1 push of a button and review on your windows computer later
• Tuner is updated with the latest firmware to make sure you have a smooth tuning process
• 1 Tune (along with your stock tune) is included in the initial price. Additional tunes are $50 each. We highly recommend 2 tunes so if poor fuel quality is an issue you can switch to a lower HP level.
• For reference; a Stock machine will dyno at 156-158 rear wheel horsepower (RWHP), 181 crank HP per factory
• Tune levels 1-4 are developed on the stock wastegate setting with stock injectors. Tunes 5 & 6 are only available with our 1200cc injectors & require adjusting your wastegate rod. We also offer all tune Levels 1 through 6 designed for the 1200cc injectors & WG rod adjustment.
• Level 1 (91-93 Octane): Tune is a modified stock power level tune but has better boost maps to help keep you in the power. We disable many limiters, raise the speed limit, rev limit, and make necessary fuel & timing changes. We maintain the max factory boost of 16.5-17 PSI.
• No wastegate adjustment required.
• Level 2 (91-93 Octane): Tune offers 17.5-18 PSI of boost with a 10-12 RWHP gain. This tune rips and can be used on a bone stock RZR in most cases.
• Suggested Mods: Billet blow-off/diverter valve and pre-airbox intake tube, clutching helps transfer the power to the wheels much more efficiently. This tune can also be used with exhaust, charge tube, and intake tube.
• No wastegate adjustment required.
• Level 3 (91-93 Octane): This tune is a game changer! Hitting hard with a gain of 20-25 RWHP, this tune offers the highest boost possible (18.5-19 PSI) on 91-93 octane fuel. Due to the upgraded Pro XP turbo with higher exhaust flow and more efficient compressor housing, we can get away with higher boost on pump gas. These are absolutely huge power gains that will have you grinning from ear to ear. This tune is built to be a max tune on 91-93 octane. If you only have access to 91 octane and fuel quality is poor or you’ll be running really hard that day, we’d suggest using a small amount of race gas or octane boost to bump your octane. This helps prevent engine knock which causes the ECU to retard your timing curve resulting in a slight power loss.
• Required Mods: High flow pre-airbox intake tube, exhaust, Billet BOV, S3 Clutch Kit.
• Suggested Mod: Charge Tube as we have seen them fail on this level.
• No wastegate adjustment required.
• Level 3.5 (93 Octane): For those wanting the absolute most out of what is achievable on pump gas – +30-35 RWHP at 19.5-20 PSI. This tune requires a minimum of 93 octane and all required supporting mods listed below.
• Required Mods: High flow pre-airbox intake tube (2020 models), exhaust, Charge Tube, Billet BOV, S3 Clutch Kit.
• Suggested Mod: Post-airbox intake tube WITH catch can
• No wastegate adjustment required.
• Level 4 (98-100 Octane): Beast mode – 200 RWHP! 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 consistently using leaded fuels can result in premature failure of O2 sensors. Now for the fun part…. this tune is INSANE and brings your Pro XP to a new level at 197-200 RWHP on our dyno. This tune gains 40-43 RWHP and pushes the boost level to 23-24 PSI peak before settling at 22-23 PSI. Keep in mind the Power Vision boost only reads to 22-23 PSI (depending on your altitude) so it will be close to maxing out the gauge. The ECU still has vision above that, but you won’t be able to read it without a manual gauge.
• Required Mods: High flow pre-airbox intake tube, exhaust, Charge Tube, Billet BOV, S3 Clutch Kit.
• Suggested Mod: Post-airbox intake tube WITH catch can, torque head bolts tighter with 120 degrees more rotation.
• No wastegate adjustment required.
• Level 5 1200cc Injectors (108-110 Octane): Beast mode times x2 – 210 RWHP! This tune is designed for 108-110 octane Now for the fun part…. this tune is INSANE and brings your Pro XP to a new level at 210 rear wheel hp on our dyno. This tune gains 50-55 RWHP and pushes the boost level to 24-25psi peak, then settles to 23-24 PSI. Keep in mind the Powervision boost only reads to 22-23psi (depending on your altitude) so it will be close to maxing out the gauge. The ECU still has vision above that, but you won’t see it without a manual gauge. There are other problems with this tune…. the speedometer struggles to keep up with the wicked acceleration and the tires won’t stop burning off!
• Required Mods: High flow pre-airbox intake tube, exhaust, post-airbox intake tube WITH catch can, Charge Tube, Billet BOV, S3 Clutch Kit. Torque head bolts tighter with 120 degrees more rotation.
• Wastegate Crack Pressure: 6.5-7 PSI (This requires shortening your wastegate rod as short as possible)
• Level 6 1200cc Injectors: Beast mode x3 – 215 RWHP! This tune is designed for E-85 fuel. Now for the fun part…. this tune is simply stupid and brings your Pro XP to a new level at 215 rear wheel hp on our dyno. This tune gains 55-60 RWHP and pushes the boost level to 24-25psi peak, then settles to 23-24 PSI. Keep in mind the Powervision boost only reads to 22-23psi (depending on your altitude) so it will be close to maxing out the gauge. The ECU still has vision above that, but you won’t see it without a manual gauge. There are other problems with this tune…. the speedometer struggles to keep up with the wicked acceleration and the tires won’t stop burning off!
• Required Mods: High flow pre-airbox intake tube, exhaust, post-airbox intake tube WITH catch can, Charge Tube, Billet BOV, S3 Clutch Kit. Torque head bolts tighter with 120 degrees more rotation.
• Wastegate Crack Pressure: 6.5-7 PSI (This requires shortening your wastegate rod as short as possible)
• Max boost levels are listed as reference only. Altitude, temperature, charge temps, intercooler temps and many other conditions play into a factor of final boost output. AA tunes do a better job of making sure you reach these levels as the factory tunes are overly safe.
• Why AA tunes over others? We have been tuning UTV’s with CVT clutches for a long time, longer than almost anyone in our field going back to the 800 RZR. Tuning a CVT vehicle properly is not an easy task as you have so many variables at one time. We spend the time to wheel dyno(with actual UTV tires) correctly per modification, and have advanced ECU calibration and clutching knowledge to do so. Every change in horsepower can result in us changing clutching several times. We also develop most of our supporting mods so we know everything works correctly, and build parts to fit the vehicles needs. Lastly and honestly the most important; we then back up our results with real world data logging on local trails and our facility on 110 acres. It’s this combination that truly makes the difference and why AA normally has a faster vehicle with the same or less rated tune horsepower.
• High Load Helix 1062: Slightly less aggressive than the performance helix with good acceleration gains/power transfer over the OEM helix. Designed to work better for heavier vehicles, heavier tires, heavy sand load or crawling type riding in mind. Excellent all around helix for any Pro XP or Turbo R/Pro S!
• Pro XP 2 Seat: Works well with 30-35″ Dirt Tires, 30-32″ dune paddles
• Pro XP 4 Seat: Works well with 30-35″ Dirt Tires, 28-32″ dune paddles
• Turbo R/Pro S 2 & 4 seat: Works well with 32-37″ tires or 30-33″ paddles
• Performance Helix 1065: Aggressive helix with acceleration/higher horsepower/aggressive fast pace drivers in mind. Works best with a tuned vehicle. Not suggested for Turbo R/Pro S 4 seat models
• Pro XP 2 Seat: Works well with 30-32″ Dirt Tires, 30-32″ dune paddles
• Pro XP 4 Seat: Works well with 30-31″ Dirt Tires, 28-30″ dune paddles
• Turbo R/Pro S 2 Seat: Works well with 32-33″ Tires.
• EBS (Engine Braking) Options:
• Keep EBS: Like factory. Most slower pace riders (mud, crawling or very hilly terrain) will keep the EBS in place. Gets rid of the chatter noise but there is a decel whine.
• Remove EBS: Removes the EBS pocket in the helix. Gets rid of the roller clunk noise but there is a decel whine. Most faster pace trail riders/racers or dune riders will choose to remove it.
