Aftermarket Assassins ‘16 Polaris RZR XP Turbo Custom Tuned Big Injectors w/ Power Vision

Aftermarket Assassins ‘16 Polaris RZR XP Turbo Custom Tuned Big Injectors W/ Power Vision

AA's performance tunes are offered loaded directly on the Powervision ECU tuner!  This versatile tuner allows our tunes to easily be uploaded to your factory ECU, switch between tunes, and even return to stock.  The is also a great gauge showing boost, timing and more. You can leave the hooked up for gauges, or completely remove it after flashing your ECU. The also has excellent data logging capabilities if you download the software, and use your laptop.  You can even view trouble codes and erase them on the fly.  We are highly experienced in tuning these RZR's and that will show. Our tunes are simply set up correctly, and everyone with a Power vision should have these tunes! They 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 Power vision allowing us to change the tire size or fan temp if needed.  These tunes are also specifically written for our larger injectors and cannot be used with your factory injectors.  When data logging with stock injectors we can see we are using over 105% duty cycle, and dyno jet's tune (because of a different way they adjust fuel) is at 114% duty cycle! These are simply numbers you do not want to see. This greatly increases the chance of injector failure, and is not nearly as precise fueling at WOT.  Polaris upgraded injectors for the 2017+ models, and you should also!  Not only did we upgrade injectors, but we imported many map fixes from the 2017 to make for a better running machine with more power and even more response.

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 our tunes over the Dyno Jet 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 Dyno Jet 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 Dyno Jet "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 tune and up are adding in race fuel and will offer even more power than any Dyno Jet 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! If you have any other needs in these tunes, or any concerns; please e-mail!

Level 1 (91 Octane):  A great increase in boost showing a +15-20 RWHP gain at 14-14.5 PSI of boost maximum.  Basically the same boost level as the factory 2017 mapping.  This tune is extremely responsive, and will be your "hold it pinned for a mile" tune.  Very easy on the motor, yet big power.  This tune works excellent with stock or aftermarket exhaust.  Stock clutching can be used, however clutching will provide better gains by properly transferring the power increase to the wheels.

Level 2 (91 Octane):  This tune offers 15-15.5 PSI of boost and a wicked +25-30 RWHP gain.  This Level 2 tune gives you reliable and big power you can hammer on all day.  Can be used with stock or aftermarket exhaust.  Clutching is necessary to properly transfer the power to the ground.

Level 3 (91-93 Octane):  This tune offers 100% maximum horsepower on pump fuel!  Running 16.5-16.8 PSI of boost max, we gain a huge +35-40 RWHP!  Requires 91-93 octane fuel. If you are running 91 octane, be sure it's non ethanol/non oxygenated.  If your area does not offer high quality pump fuel, a half can of VP Madditive or Torco Accelerator will work.  A small mix of a 1/2 gallon race fuel would also work to boost the octane to a safe level.  Aftermarket exhaust is highly recommended.

Level 4 (96-100 Octane):  This tune runs 17.2-17.7 PSI max and really throws down the hammer!  A huge +45-50 RWHP gain is seen with this boost pressure.  This tune requires 96-100 octane fuel.  For most people, this will be a full can of VP Madditive or Torco Accelerator per tank, or 2 gallons of 110 race fuel or better per tank.  We also recommend shortening your waste gate actuator rod by 1.5-2 turns to prevent the waste gate from opening slightly, and limiting boost.

Level 5 (110 Octane):  This tune really ignites the fire with gains of +50-55 RWHP!  This tune is developed for 110 octane fuel (unleaded is recommended if you plan on running your O2 sensor, as leaded fuel will reduce the life of the sensor).  We add just a little more boost to our Level 4 running you at 17.7-18 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 makes this tune come out of hole even harder and keep pulling for days.  In testing over our Level 3 tune, we had to add 3 grams of clutch weight to run the same RPM.  If you are racing, or really want to show you're buddies who's boss... this is the tune you want!  We also recommend shortening your waste gate actuator rod by 1.5-2 turns to prevent the waste gate from opening slightly, and limiting boost.

Level 6 (E-85):  Have E-85 local to you?  Time to fill up and start turning heads!   E-85 is a great race fuel replacement as it runs very cool and can sustain high boost with advanced timing maps...which equals awesome power without breaking the bank every time you fill up! We crank out all that our Level 5 tune has and push it even a little more.  Keep in mind E-85 takes about 30% more fuel to run, so it will guzzle fuel fast. Aftermarket exhaust, BOV, & clutching are also required.   Crack pressure should be set at 6.5-7 PSI.
