Aftermarket Assassins '11-'14 Polaris RZR XP 900 Custom Tunes CX 3 & 4 for Power Vision

• 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 900. If you are looking to tune two vehicles with your Powervision 3 (Not applicable to PVCX or PV4) please read this page thoroughly before proceeding. If tuning two vehicles with your PV4, the app will prompt you to purchase a License for the additional vehicle. 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.  We need you to send your PV_INFO file to us before we can send the tunes. For more information on how to get this, see the below description, or this VIDEO (PV3 only in video).
• Big horsepower gains! The factory timing map is very detuned on the XP 900 models, along with a few key areas of mapping that is lacking. 
• MUCH quicker throttle response and power delivery
• AA's wicked timing curve is set up for 91 octane and delivers a huge punch in the mid-range and much better top end power
• A great fuel curve that gives much better low end(as well as all around) power as the factory map is very lean in key areas.
• Fan on/off temp lowered to 185/180 degrees Fahrenheit
• Rev limit at a safe 9000 RPM (Stock is 8400 RPM)
• Best peak power when tuned is 8000-8200 RPM at wide open throttle around 55 MPH
  • Level 1:  A huge increase and is developed for a bone stock RZR XP 900. This is seriously worth every penny!  You are looking at an average 5-6 HP gain on pump gas with the tune, but the down low grunt is absolutely awesome.   
  • Level 2:  Meant for a RZR XP 900 with stock exhaust and a high flow intake.  It has all the same benefits as Level 1 but with increased fueling for the intake. The intake is highly restricted on these models, so we highly suggest this setup if wanting to stay with the stock exhaust.  For an intake kit, we suggest the Desertcraft Double Down kit. Together with a tune and intake you can see 8-10 RWHP gains! 
  • Level 3:  Meant for a RZR XP 900 with an aftermarket exhaust & high flow intake.  It has all the same benefits as previous levels but with increased fueling for the exhaust & intake. This tune will work on a stock intake with exhaust, but we highly suggest adding the high flow intake for best performance.  Together with a tune, intake and exhaust you can see 12-15 RWHP gains! Will work with slip-on or full exhaust.
  • Level 4:  Meant for a RZR XP 900 with a big bore motor, aftermarket exhaust, and high flow intake.  It has all the same benefits as previous levels but with increased fueling & timing for the big bore/exhaust & intake. This tune would work on a vehicle with the stock exhaust and big bore motor also, but you really need a high flow intake for this to perform properly.  Depending on the motor work, the potential horsepower gains can be 20-25 RWHP over stock!  Will work with slip-on or full exhaust. Keep in mind big bore tuning may require customization and these tune changes are $50 each and require adding the DynoJet wideband module for $450 to view and log air/fuel ratios.
• Wondering why go with our tune(s) over the DynoJet tunes? We go the extra mile to make sure everything is gained, and have a few extra tricks up our sleeve because we test in the real world. Other maps take their time to hit peak timing numbers which really hurts performance. Our map gets you into peak timing quicker, so max power seems more instant. We also have a great fuel curve that is designed to go with our timing curve, and offers better fueling for more power at WOT.  Basically, this is the all out tune that has all the features you want built right into it. 
• To help better transfer the power gained to the wheels, and to achieve proper peak RPM, we highly recommend our AA Recoil clutch kits!
