Aftermarket Assassins Big Turbo Tunes for Powervision For Polaris RZR Turbo / RZR XP Turbo 

Big turbo tunes for your 2016-21 RZR XP Turbo or Turbo S with a larger turbo or OEM turbo with turbo modification

• Are you looking for the most badass tunes available for your Powervision? Here you are! These tunes are for customers that already have the Powervision for the RZR XP Turbo & Turbo S. We are highly experienced in tuning the RZR models and that will show. Our tunes are also easily labeled and will show rough horsepower claims with supporting mods such as exhaust and clutching. These tunes modify all the necessary maps to create big horsepower, while still maintaining a reliable and safe RZR.  Each tune is built specifically for your Powervision allowing us to change the tire size or fan temp if needed. 
• Tunes will be made to work with DynoJet turbo, Silber turbo, Agency Turbo, Pro XP turbo, Boondocker turbo... etc.  Please let us know your wastegate turbo crack pressure (PSI @ which the wastegate actuator arm begins to move)
• Tunes are shown with the price assuming you already have a DynoJet PV3 tuner.  If you do not and need to purchase one, you can select to purchase in the drop down menu.
• While we highly suggest purchasing our turbocharger from us for the best results, these tunes will work with most aftermarket turbochargers or turbo mods such as the Dominator, Agency... etc..   We have many requests for these tunes as customers have not been happy with other tuning solutions.
• Tunes must use our 7-18 PSI actuator with the spring that comes standard in them, set to 7 PSI for Pro XP style turbos or 10-12 PSI crack pressure for other style turbos (Ex: our Original Water Cooled Turbo):  AA Billet Wastegate Actuator
• You must also use either OEM injectors or AA 1200cc injectors.  We will not tune for any other injectors
• Tunes are sold as is and known to work very well with many turbos in the field so far.  Because of the variety of turbos, you may need some small tweaks if you have any overboost or under boost codes.  If your tune needs adjustments to work with a custom setup, they are $50 per adjustment after reviewing data logs.
• Ready to step up to the next level on your XPT and gain some serious power? Up to 255-260 crank horsepower with our big turbo tunes!
• ECU Type/O2 Color drop down choice:
  • 2016-18 models: ALL have the standard narrowband black O2 lead.
  • 2019-20 models: Some have the standard narrowband black O2 lead while others with a blue O2 lead are wideband models.  These models are a different ECU type and will NOT do an ECU read (we can supply your stock file if you have never flashed your ECU before with your device).  
  • 2021 models:  ALL have the wideband blue O2 lead.
• 19-21 Wideband models normally do not need a fuel pump upgrade, the OEM pump works fine even for E85 fuel
• Stock-like driveability!
• Gain another 10-15 RWHP on pump gas tunes over the factory turbo
• Our dyno results on our 2019 Turbo S stock is 137-138 RWHP.  A standard XPT has less aggressive clutching and will show 134-135 RWHP stock.  
  • The Level 2 big turbo tune is a very safe 16-17 PSI 91 octane tune, good to run on any 91 oxy/ethanol.  This tune produces 155-160 RWHP peak (calculated 195 crank HP), but will pull much harder and keep that horsepower maintained much better than the stock turbo.
  • The Level 3 big turbo tune offers 18-19 PSI and is also meant to run on 91-93 octane fuel.  This produces 175 RWHP (calculated 220 crank HP) and comes on unbelievably strong, and keeps pulling.  Those with 91 non ethanol, or 93 even with ethanol will be fine on straight gas.  Those with oxygenated  91 might want to think about adding splash of race fuel or VP Octanium/Boostane fuel additive.
  • The Level 3.5 big turbo tune offers 19-20 PSI and is meant to push the limits of pump gas with a 93 octane minimum.  This produces 180 RWHP (calculated 225 crank HP) and comes on even stronger than our Level 3 and keeps pulling.
  • The Level 4 big turbo tune is for 98-100 octane fuel. This will produce 185-187 RWHP (calculated 240 crank HP) at 22-23 PSI and hauls the mail!  Most will mix race fuel with pump fuel to get the 100 octane which is what we recommend.  A can of Octanium/Boostane to your tank will also work with this tune.  While we suggest tightening head bolts or adding studs, many have a been fine without.   Version 3 catch can is suggested, but version 1 will be okay with this setup.
  • The Level 5 big turbo tune is for 110 octane fuel and simply drops the hammer!  You'll have everyone wondering what is done to your RZR with this bad ass tune.  A huge 25-26 PSI of boost that comes on HARD.  This tune produces 200-205+ RWHP (calculated 250-260 crank horsepower) on our dyno, and has shown 215-220 on customer dynos. We normally run this tune on 110 leaded fuel.  Leaded fuel is harder on O2 sensors but we have not had much of an issue.  We would suggest picking up another O2 sensor if running leaded fuel (we have them available). 
  • The Level 6 E-85 big turbo tune is simply unbelievable. Very similar to the 110 tune power, but runs on cheap corn (E85) fuel! This can also be ran on VP or other E85 fuels.  This fuel makes the motor run cooler and it absolutely loves it.  If using pump E-85, make sure you are between 70-85% ethanol for this tune.  25-26 PSI with a wicked timing curve that produces the same 200-205 RWHP.  This tune requires our 1200cc injectors and our high flow fuel pump.  The injectors are included in the price of the Level 6 tune. Selecting Level 6 will result in all tunes being built to run 1200cc injectors. You MUST run the 1200cc injectors with all tunes if selecting this option. 
• Supported mods needed for all levels:  AA big turbo tunes for PV, AA high flow intake tube, AA high flow charge tube, AA S3 clutch kit, AA blow off valve, AA slip-on exhaust (or a slip-on exhaust that is free flowing). Power levels are shown with the AA exhaust with no quiet core installed (both outlets open).
• Supporting mods for level 4:  Level 4 can be run on the same supporting mods as above, but you NEED the Pre airbox intake tube .   We recommend having an oil catch can and tightening the head bolts to 85ft-lbs OR adding head studs.   Many have run level 4 without head studs or the catch can, but we suggest it for motor safety.  We also suggest to gap the spark plugs at .020" (NGK Iridium plugs highly recommended as we have seen issues with the OEM plugs).
• Additional supporting mods needed to run level 5-6:  Tighten head bolts to 85ft-lbs or install ARP studs to 85ft-lbs (95 if using custom age 625+ studs), gap plugs to .020", catch can (version 3 is highly suggested), and pre airbox intake tube is needed!
• 2016 models will need our 2017 style injectors and upgraded fuel pump for level 2-5.  If wanting to upgrade to E85 big turbo tunes, you will need our 1200cc injectors and fuel pump.  If going with the 1200cc injectors, we'd build all of your tunes for those injectors.
