Aftermarket Assassins Big turbo tunes for your 2020+ RZR Pro XP / Turbo R / Pro S with a larger turbo or OEM turbo with turbo modification

• Are you looking for the most badass big turbo tunes available for your Powervision? Here you are! These tunes are for customers that already have the Powervision and a big turbo for the RZR Pro XP/Turbo R/Pro 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, Boondocker turbo... etc.
• 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 customer 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 7-8 PSI crack pressure:  AA Billet Wastegate Actuator
• You must also use either OEM injectors or AA 1200cc injectors.  We will not tune on any other injectors
• Tunes are sold as-is and are 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 underboost codes.  If your tune needs adjustments to work with a custom setup, they are $95 per adjustment after reviewing data logs.
• Ready to step up to the next level on your Pro XP/Turbo R and gain some serious power? Up to 320-330 crank horsepower with our big turbo tunes with a built motor and race gas!
• **** RUNNING OVER 25-26PSI (LEVEL 5 or 6) REQUIRES A BILLET CRANK***** You can test the waters with the OEM crank, but most likely you will have issues. Most would pair this turbo with a built motor with:  Brian Crower Billet Crankshaft, Carillo Rods, CP Pistons, custom age ARP head studs.   A fire ring cylinder or K&T big bore cylinder are great options as well.   Cylinder head porting, oversize exhaust valves and BC custom ground camshafts are also good modifications to add slightly more power.
• Running level 4 or higher requires all of our bolt-on modifications plus the catch can.
• Level 5 & 6 require our 1200cc Injectors (All other tune levels will be built for 1200cc Injectors when selecting Level 5 or 6)
• All tunes were developed by one of the most experienced RZR turbo tuners, and tuned to maximum power for each specific fuel grade.  Our dyno normally reads a bit low compared to some, so keep that in mind.... our stuff normally outruns the competition with the same HP level.  This is also due to the fact that we make nearly all components/clutching to properly transfer and make power.  - Mike
  • We skip level 1
  • Level 2:  Built for 91 octane, +15-20 RWHP. Gains similar to our OEM turbo Level 2 tune, with around 5 more RWHP from the increased turbo exhaust flow.  No huge gains over OEM turbo, this tune is simply setup for the larger turbo. Great driveability and good fuel economy for trail riding.  You will see cooler intake temps with this big turbo tune vs the OEM turbo.
  • Level 3: Built for 91-93 octane,  This tune produces around 7-9rwhp  more than the OEM tune due to the higher exhaust flow. It's an 18-19.5 psi tune and produces 182-185rwhp or 230 crank hp.  You will see cooler intake temps with this big turbo tune vs the OEM turbo.
  • Level 3.5:  Built for 93 octane, this tune is for those wanting the absolute most out of what is achievable on pump gas.  It's a 19.5-20 PSI tune and produces 192-195 RWHP or 240 crank HP.  You will see cooler intake temps with this big turbo tune vs the OEM turbo.
  • Level 4: Built for 98-100 octane fuel, and will run fine on octane higher than 100 as well. This will produce 220-225 RWHP (calculated 270-280 crank hp) at 23-24 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 VP Octanium or Boostane to your tank will also work with this tune. This gains you roughly 20rwhp over the OEM turbo level 4.  This tune is pushing it on the OEM crank, but in most cases will run on an OEM motor with the head bolts tightened to 85ft-lbs, or head studs installed.  It will be safer to run on a built motor.  
  • Level 5: Built 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.  The standard tune is 26-27psi for all day running around 245rwhp (290-300 crank), BUT we have the RACE tune which pushes a huge 28-29 PSI of boost that comes on HARD.  This RACE tune produces 261+ RWHP (calculated 310-320 crank horsepower) on our dyno.  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 this tune, or you can run MS109 unleaded fuel.
  • Level 6: Built for E-85, this big turbo tune is simply unbelievable. Very similar to the 110 tune power with both the standard 26-27psi tune and the higher boost RACE tune. The difference is this tune runs on cheap corn fuel, or expensive VP corn fuel!  This fuel makes the motor run cooler and it absolutely loves it.  The only downfall is you go through more fuel, and push more fuel into the crankcase, and into the catch can(necessary mod).  If using pump E-85, make sure you are between 70-85% ethanol for this tune.
    • RACE tune is 28-29 PSI with a wicked timing curve that produces the same 267rwhp or 320-330 crank hp.
• Supported mods needed:  AA big turbo tunes for PV, AA high flow intake tube, AA high flow charge tube, AA clutch kit, AA blow off valve, AA slip-on exhaust or a slip-on exhaust that has the same flow. Power levels are shown with the AA exhaust with no quiet core installed.
  • Level 4-6 require head bolts to torqued to 85ft-lbs (or custom age 625+ studs) and our catch can intake tube or additional valve cover/atmospheric vented catch can
  • Level 5 & 6 RACE tunes require the additional catch can, custom AGE 625+ studs torqued to 95ft-lbs, and should have a built motor with a billet crank, CP pistons, and rods.  Race tunes are mostly for drag racing and should be run at your own risk for extended periods of time.  They would also be at risk of breaking the crankshaft on the OEM motor.
