•  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 Pro XP. 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 other features 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. 
• Works with all 2020 RZR Pro XP Turbo models including Dynamix models.  The Pro XP Turbo is an animal waiting to be unleashed.  This models uses a factory upgraded turbo able to create more boost at lower temps quite like our turbo mod for the earlier version RZR XP Turbo.  This allows us to push the limits further with just a tune.  Several improvements including stronger head bolts allow the motor to handle the extra boost.  
• Big horsepower gains depending on the level of tune desired
• Quicker throttle response and power delivery
• Throttle by wire limiters disabled
• Fan on/off at 185 degrees Fahrenheit (Stock is 190).  The fan also ramps up in power quicker to keep you running cool.
• Optional start in any gear! Does not need to be in park to start. Will start without brake, but may throw a code.  Press brake to start until we figure this issue out.  Keep in mind this is removing a safety feature. 
• Seat belt limiter disabled
• Speed limiter removed in low and high gears
• More throttle % and boost in low gear and reverse
• Rev limit at a safe 9300 RPM
• For reference; a Stock machine will dyno at 156-158 rear wheel horsepower, 181 crank HP per factory
• Tune levels 1-4 are developed on the stock wastegate setting with stock injectors.  Tunes 5 & 6 are only available with our 1200cc injectors & require adjusting your wastegate rod.  We also offer all tune Levels 1 through 6 designed for the 1200cc injectors & WG rod adjustment.
• The Level 1 tune is a modified stock power level tune but has better boost maps to help keep you in the power.  We disable many limiters, raise the speed limit, rev limit, and make necessary fuel & timing changes. We maintain the max factory boost of 16.5-17 PSI.
• The Level 2 tune offers 17.5-18 PSI of boost with a 10-12 RWHP gain.  This tune rips and can be used on a bone stock RZR in most cases. We highly recommend our billet blow-off/diverter valve and pre airbox intake tube. While not required, clutching helps transfer the power to the wheels much more efficiently. This tune can also be used with exhaust, charge tube, and intake tube.... etc.  No wastegate adjustment required.  91-93 Octane tune.
• The Level 3 tune is a game changer! Hitting hard with a gain of 20-25 RWHP, this tune offers the highest boost possible (18.5-19 PSI) on 91-93 octane fuel.  Due to the upgraded Pro XP turbo with higher exhaust flow and more efficient compressor housing, we can get away with higher boost on pump gas. These are absolutely huge power gains that will have you grinning from ear to ear.  This tune is built to be a max tune on 91-93 octane. If you only have access to 91 octane and fuel quality is poor or you'll be running really hard that day, we'd suggest using a small amount of race gas or octane boost to bump your octane. This helps prevent engine knock which causes the ECU to retard your timing curve resulting in a slight power loss.  Required Mods: High flow pre airbox intake tube, exhaust, Billet BOV, S3 Clutch Kit.  Suggested Mod: Charge Tube as we have seen them fail on this level.  No wastegate adjustment required.
• Level 4 - Beast mode - 200 RWHP!  This tune is designed for 98-100 octane (will run on UTV 96, or most fuels up to 110 octane) and was developed using one can of VP Octanium to a tank of fuel.  Mixing other race fuel with the tune to get 100 octane output would work great, just keep in mind consistently using leaded fuels can result in premature failure of O2 sensors.  Now for the fun part.... this tune is INSANE and brings your Pro XP to a new level at 197-200 RWHP on our dyno. This tune gains 40-43 RWHP and pushes the boost level to 23-24 PSI peak before settling at 22-23 PSI. Keep in mind the Power Vision boost only reads to 22-23 PSI (depending on your altitude) so it will be close to maxing out the gauge.  The ECU still has vision above that, but you won't be able to read it without a manual gauge.  Required Mods: High flow pre airbox intake tube, exhaust, Charge Tube, Billet BOV, S3 Clutch Kit.    Suggested mod:  After airbox intake tube WITH catch can, torque head bolts tighter with 120 degrees more rotation.   No wastegate adjustment required. 
• Level 5 1200cc Injectors, Waste Gate Rod Shortened - Beast mode times x2 - 210 RWHP!  This tune is designed for 108-110 octane  Now for the fun part.... this tune is INSANE and brings your Pro XP to a new level at 210 rear wheel hp on our dyno. This tune gains 50-55rwhp on pushes the boost level to 24-25psi peak, then settles to 23-24psi. Keep in mind the powervision boost only reads to 22-23psi (depending on your altitude) so it will be close to maxing out the gauge.  The ECU still has vision above that, but you won't without a manual gauge. There are a few other problems with this tune.... the speedometer struggles keep up with the wicked acceleration, and the tires won't stop burning off.  Required Mods: High flow pre airbox intake tube, exhaust, Intake tube with catch can, Charge Tube, Billet BOV, S3 Clutch Kit.   This requires shortening your wastegate rod as short as possible to 6.5-7psi crack pressure.   Also requires torquing head bolts tighter with 120 degrees more rotation. 
• Level 6 1200cc Injectors, Waste Gate Rod Shortened - Beast mode x3 - 215 RWHP!  This tune is designed for  E85 fuel.  Now for the fun part.... this tune is simply stupid and brings your Pro XP to a new level at 215 rear wheel hp on our dyno. This tune gains 55-60rwhp on pushes the boost level to 24-25psi peak, then settles to 23-24psi. Keep in mind the powervision boost only reads to 22-23psi (depending on your altitude) so it will be close to maxing out the gauge.  The ECU still has vision above that, but you won't without a manual gauge. There are a few other problems with this tune.... the speedometer struggles keep up with the wicked acceleration, and the tires won't stop burning off.  Required Mods: High flow pre airbox intake tube, exhaust, Intake tube with catch can, Charge Tube, Billet BOV, S3 Clutch Kit.   This requires shortening your wastegate rod as short as possible to 6.5-7psi crack pressure.   Also requires torquing head bolts tighter with 120 degrees more rotation. 
• 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, and have the EPA to deal with.

• Oh... and get ready for your RZR to flat out rip!
