  • ***Fits 2018-22 X3 120 horsepower base, non-intercooled X3***  
  • The Maverick X3 120HP is a great UTV that has a ton of potential.  It's priced right, and for just a little more we can get the power you are needing. 
  • Initial 120HP to 185HP Upgrade Kit includes: PV3 tuner, Intercooler with Fan, S2 clutch kit, BOV, and charge tube & clamps.  You can then opt to upgrade to the 172hp fuel pump to add even more power up to 230HP  
  • We have 3 levels of performance for pump gas on the intercooler/stock fuel pump configuration up to 185HP.  For those who upgrade to the 205HP upgrade kit, which adds the 172HP fuel pump kit, we have 6 levels of performance from pump gas up to 205HP, to race fuel and E-85 up to 230HP! Tunes are now intercooler/fan ready with no need for an additional harness/switch.
  • If you choose to add the 172HP fuel pump later on you can purchase tunes for this as well at a later time here!  These tunes are built off the 120HP base tune, but have all the same updates/horsepower levels as the 172HP X3's.
  • 2018-19 models require upgrading to a high flow intake or a 2020+ airbox.
  • OEM shroud over intercooler is NOT used
  • Exhaust (cat delete is fine) highly suggested for Level 3 or higher to run at optimum performance
  • If you are looking for the most badass custom tunes that are easily loaded to your X3 from the Dynojet Powervision, you've found them!  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 PV is also a great gauge showing boost, timing and much more. You can leave the Powervision hooked up for gauges, or completely remove it after flashing your ECU. The Powervision 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 ECU tuning and it shows. Our tunes are simply set up correctly, and everyone with a Powervision should have these tunes! They are also easily labeled and will show horsepower gains 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 X3.  Each tune is built specifically for your Powervision allowing us to change various things like rev limit or fan temp if needed.
  • Big horsepower and torque gains depending on the level of tune desired, and supporting modifications.
  • Not just dyno tested! We are avid riders and like the factory, a ton of the testing is done in the field to make sure you are getting 110%.  With data logging capabilities you can't get any better testing than real world.  Often times we can make significant changes to further increase power, drivability, and feel of the machine that can never be done on the dyno.
  • Wicked throttle response and power delivery (for sport mode)
  • Throttle by wire limitations disabled
  • Torque calculations set correctly to ensure the most performance at all times
  • Fuel tables modified to gain low end punch and safe yet powerful AFR
  • Get rid of the lean punch!  The factory runs these things stupid lean when getting on boost and we fix that.
  • Boost tables properly modified for the fuel & modifications along with lightning quick turbo spool
  • Timing tables modified for best power per tune
  • Safety parameters to protect your motor and turbocharger are still in place
  • Speed limiters removed with the white key
  • 2 foot limiters removed
  • Rev limit raised from 8300 to a safe 9000 RPM
  • Powervision flash tuner reprograms your ECU in roughly 8-10 minutes per flash over the diagnostic port
  • Easily return back to stock, switch tunes, or upgrade tunes at any time
  • A great gauge (see live boost and more) and data logging device
  • See our Powervision gauge mount HERE
  • For reference the stock 120HP base is roughly 7 PSI of boost
  • Our level 1 tune for a 120hp with intercooler and stock fuel pump produces roughly 170 crank horsepower on 91 or 93 octane.  This tune runs an average of 14 PSI of boost and is a very safe tune to run on even 91 oxy/ethanol fuel. This tune absolutely rips on 14psi, and puts your right on par with the 172hp model horsepower!   2018-19 models can upgrade to our high flow intake and gain another 5-7hp. Will work with our without an aftermarket exhaust. **Required Mods: Clutch kit, wastegate crack pressure at 7-8psi.**
  • Our level 2 tune for a 120hp with intercooler and stock fuel pump produces roughly 180 crank horsepower on 91 or 93 octane.  This tune runs an average of 14.5-15psi of a boost. 2018-19 models can upgrade to our high flow intake and gain another 5-7hp. Will work with our without an aftermarket exhaust. **Required Mods:   clutch kit, wastegate crack pressure at 7-8psi.**
  • Our level 3 tune for a 120hp with intercooler and stock fuel pump produces roughly 185 crank horsepower on 91 or 93 octane.  This tune runs an average of 15-15.5psi of a boost.  This tune is our max pump gas tune and hauls the mail.  2018-19 models can upgrade to our high flow intake and gain another 5-7hp. **Required Mods:  Aftermarket exhaust (at least cat delete), clutch kit, wastegate crack pressure at 7-8psi.**
  • Our level 1 tune for a 120hp with intercooler and 172hp fuel pump produces roughly 185 crank horsepower on 91 or 93 octane.  This tune runs an average of 15-16psi of a boost.  2018-19 models can upgrade to our high flow intake and gain another 5-7hp and lower boost temps. **Required Mods:   clutch kit, wastegate crack pressure at 7-8psi.**
  • Our level 2 tune for a 120hp with intercooler and 172hp fuel pump produces roughly 195 crank horsepower on 91 or 93 octane.  This tune runs an average of 16-17psi of a boost.  2018-19 models can upgrade to our high flow intake and gain another 5-7hp and lower boost temps. **Required Mods:  clutch kit, wastegate crack pressure at 7-8psi.**
  • Our level 3 tune for a 120hp with intercooler and 172hp fuel pump produces roughly 205 crank horsepower on 91 or 93 octane.  This tune runs an average of 17-17.5psi of a boost.  2018-2019 models must have a high flow intake(2020+ models already have a high flow intake).  **Must have aftermarket exhaust (at least cat delete).  Must have clutching, Wastegate crack pressure should be 7-8psi.**
  • Our level 4 tune for a 120hp with intercooler and 172hp fuel pump produces roughly 220 crank horsepower on 98-100 octane.  We normally run 91 or 93 octane with 1 can of VP Octanium unleaded.  This tune runs an average of 18-18.5psi of a boost with a hotter timing curve to pick up extra torque and hp. This tune is wicked fast!  **2018-2019 must have a high flow intake (2020+ models already have a high flow intake).  Must have aftermarket exhaust (at least cat delete).  Must have clutching, Wastegate crack pressure should be 9-10psi.**
  • Our level 4 AV gas tune for a 120hp with intercooler and 172hp fuel pump produces roughly 220 crank horsepower and has the same requirements as the original level 4.
  • Our level 5 tune for a 120hp with intercooler and 172hp fuel pump produces roughly 230 crank horsepower on 105-110 octane.  We normally run MS109 as it's unleaded.  This tune runs an average of 19-20psi of a boost with a hotter timing curve even over level 4 to further pick up extra torque and hp. This tune is crazy fast for the stock turbo!  Hands down, this is the highest horsepower tune possible on the factory turbo/waste gate & factory injectors.  **2018-2019 must have a high flow intake (2020+ models already have a high flow intake).  Must have aftermarket exhaust (at least cat delete).  Must have clutching, Wastegate crack pressure should be 10-12psi.**
  • Level 6 E85 Kill mode for the 120hp with intercooler, 172 fuel pump, and our 1200cc injectors produces 230 crank HP  This E85 tune packs as much if not more punch than the level 5 tune but must be used with our big injectors.  This tune is an absolute riot and will leave others in the dust.  We throw down a huge 185-190 RWHP with this tune at 19-20 PSI of boost, with a wicked timing curve for the cool burning E85.  This one will throw you back in the seat as soon as you get on the throttle, and keep pulling for days!  Hands down, this is the highest horsepower tune possible on the factory turbo/waste gate.  **2018-2019 must have a high flow intake (2020+ models already have a high flow intake).  Must have aftermarket exhaust (at least cat delete).  Must have clutching, Wastegate crack pressure should be 10-12psi.  If purchasing this tune it will automatically include the injectors.  Your other tunes purchased will also be built for the 1200cc injectors (tunes must be written for those specific injectors)**
  •  How to:  Waste Gate Adjustment 
  • 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 AA tunes over others?  We have been tuning UTV's with CVT clutches for a long time, longer than almost anyone in our field going back to the 800 RZR.  Tuning a CVT vehicle properly is not an easy task as you have so many variables at one time.  We spend the time to wheel dyno(with actual UTV tires) correctly per modification, and have advanced ECU calibration and clutching knowledge to do so. Every change in horsepower can result in us changing clutching several times. We also develop most of our supporting mods so we know everything works correctly, and build parts to fit the vehicles needs.  Lastly and honestly the most important; we then back up our results with real world data logging on local trails and our facility on 110 acres.  It's this combination that truly makes the difference and why AA normally has a faster vehicle with the same or less rated tune horsepower.
  • S2 Clutch kits include 3 of our AA Recoil magnetic adjustable clutch weights (uses your 3 stock arms), our primary spring & setup guideline.  You can choose to upgrade to the S3 kit which includes all 6 clutch arms and our adjustable helix for $525 extra. See the adjustable helix page for more information on helix options.
