Aftermarket Assassins Tuner 2011-2014 RZR XP 900

Aftermarket Assassins Tuner 2011-2014 RZR XP 900

• 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. 
  
• AA's wicked timing curve built for the fuel tune you choose
  
• 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
  
• Seatbelt limiter disabled
  
• 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 55mph
  
• See how to install and use the tuner in this VIDEO
  
• Very easy to use tuner that can also check and erase most trouble codes
  
• Easily data log 25 parameters with 1 push of a button and review on your windows computer later
  
• No mess of having to send in your ECU, and a safer way of programming your ECU
• The Level 1 tune is 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.   
  
• The Level 2 tune is built for the stock exhaust with 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! 
  
• The Level 3 tune is built for 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.
  
• The Level 4 tune is built for 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 20-25rwhp 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 adding the dynojet wideband module for $350 to view/log air/fuel ratios.  
  
• To help better transfer the power gained to the wheels, and to achieve proper peak RPM, we highly recommend our AA Recoil clutch kits! 
  
• Due to the time to it takes to custom program these tuners, we will ship within 24-48 hours of purchase.
