  • Kit fits 2018-21 172HP Base X3's or 2017 X3's with the 2018-21 style fuel pump (2017 models MUST have 2018-21 style fuel pump)
  • 2020-21 Models with the updated airbox do not need the intake.  This will be subtracted from the price when selecting year.
  • Lock & Load!  This Stage 2 kit provide a big increase in horsepower and torque simplified into an easy package.  Tuning, clutching exhaust, and intake on the 172 base HP X3 go together like high powered rifles and tannerite.  Together they pack a huge punch for the ultimate power gains to the wheels.  The tuning allows for great power depending on the level tune, supporting mods & fuel you want to run.  Tuning also allows for better power at higher RPM where the factory ECU calibration falls off. The clutching allows for RPM to ramp up faster, and to reach those higher RPM where best power to the wheels is made in the real world.  Exhaust helps get rid of unneeded back pressure and heat to help run more boost at cooler temps, while gaining power.  The high flow intake also reduces temps and horsepower by providing less restricted airflow to the turbo.  This kit also includes the catch can which is a closed loop system which is the right way as you use the negative pressure from the intake to draw pressure out of the bottom end. The blow off valve helps to keep the turbo safe when running higher boost.  
  • If you have a stock X3 (performance parts wise) this kit is best combined with the Level 3 tune or higher.  With the catch can and BOV this kit has no problem running the highest level tunes.
  • Gains shown and listed are for 2018-21 base power (139 RWHP).  2017 base power was 126 RWHP.
  • The 2018-21 Maverick X3 172 base HP is a great machine with good power from the factory, but whey stop there?  This 3 cylinder turbocharged motor has so much more potential!  After many hours testing on the dyno, and even more testing in the real world, we have what we believe to be the best tunes on the market for the 2018-21 X3, or 2017 models with the upgraded fuel pump.  We modify many parameters and spent a TON of time fixing a few issues we saw from the factory when cranking up the boost.  
  • 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. We tune to max power for the fuel & supporting mods.  You won't find more power no matter what others claim.  We also have a longer history than nearly all competitors of tuning CVT transmission vehicles with turbochargers.
  • Throttle by wire limitations disabled giving wicked throttle response and power delivery (for sport mode)
  • Torque calculations set correctly to ensure the most performance at all times
  • Fuel tables modified to gain low end punch and safe yet powerful air/fuel ratios
  • 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 or raised depending on gear
  • 2 foot limiters removed & Start in any gear
  • Rev limit raised from 8300 to a safe 9000 RPM
  • Powervision flash tuner reprograms your ECU in roughly 8-10 minutes & easily installs by plugging into your 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
  • For reference; 2018-21 X3 172HP models dyno at 139 RWHP and 2017 X3 154HP models dyno at 126 RWHP.  172HP model gains shown below.  Tune Levels 1-5 are developed for OEM injectors.  Tune Level 6 requires our 1200cc injectors - If selecting Level 6 & 1200cc injectors, all other tunes will be built for 1200cc injectors.
    • Level 1 (91-93 Octane): Designed for a completely stock X3 on 91 octane or better.  This tune runs an average of 15-16 PSI of boost and is a very safe tune to run on even 91 oxy/ethanol fuel.  Gains are right around 10-12 RWHP.  Many competitors only offer a max pump gas tune and that simply does not work well without having a good quality 91 non-ethanol or 93 octane fuel.  If you run into poor quality fuel, your safety circuits will pull timing based on DET and can even go into a partial limp mode dropping you down to below stock boost levels.  Our Level 1 is a great tune to have available for such an event that you get bad fuel.. it still rips and just keeps pulling all day long, but won't push the limits as much.  Works well with a 100% stock machine or with a slip-on exhaust, cat delete, full exhaust, and/or an intake kit.
      • Wastegate Crack Pressure: No wastegate adjustment required for 2018-21 Models (7-8 PSI). 2017 models w/18 fuel pumps adjust 2-3 turns.
    • Level 2 (91-93 Octane): Designed for 91-93 octane and is our max tune on the stock exhaust.  This tune is absolutely nuts for being able to run on a bone stock X3..  Boost comes on hard and keeps pulling like an animal.  Peak boost is around 17-18 PSI, and settles down to roughly 16-17 PSI.  We spent a huge amount of time tuning and reviewing logs on pump gas to squeeze everything possible on 91 pump gas, and this is it. Gains are right around 18-20 RWHP. You simply can't find a more powerful tune on a stock X3 172 base.
      • Suggested Mods: Full exhaust, high flow intake kit, clutch kit.
      • Wastegate Crack Pressure: No wastegate adjustment required for 2018-21 models (7-8 PSI). 2017 models w/18 fuel pumps shorten rod 2-3 turns (7-8 PSI).
    • Level 3 (91-93 Octane): Puts the hammer down on 91-93 octane!  Like our Level 2, this tune simply rips on pump gas but requires a full exhaust and high flow intake to run 91 octane.  If you run 93 octane (or boost your 91 to 93) you can run this tune on the factory exhaust (however you'll be leaving power on the table). It will peak around 18-19 PSI and sustain around 17-17.5 PSI.  This is a big 23-25 RWHP gain over factory.
      • Required Mods: Full exhaust and high flow intake kit.
      • Suggested Mods: Clutch Kit
      • Wastegate Crack Pressure: No wastegate adjustment required for 2018-21 models (7-8 PSI). 2017 models w/18 fuel pumps shorten rod 2-3 turns (7-8 PSI).
    • Level 4 (98-100 Octane): Adds a bit of race fuel to the mix!   This tune is designed for 98-100 octane (will run on UTV 96) and was developed using one can of VP Octanium Unleaded to a tank of fuel.  Mixing 110 race fuel with pump gas to get 100 octane works great, just keep in mind leaded fuels decreases the life of O2 sensors when running leaded fuel consistently. This tune runs around 18-18.5 PSI and produce up to 174 RWHP (+33-35 RWHP) and is extremely fast.
      • Required Mods: Full exhaust and high flow intake kit.
      • Suggested Mods: Clutch Kit
      • Wastegate Crack Pressure: 2018-21 models shorten rod 2 turns (9 PSI).  2017 models w/18 fuel pump shorten rod 4-5 turns (9 PSI).
    • Level 4AV (100LL): Same as the Level 4 tune but designed to run 100 LL AV gas found at your local airport.  This fuel has a different specific gravity with additional oxygenation and other characteristics.  Running a tune not meant for this fuel can make it run lean and therefore you will not get the full power and potential from the fuel.  This tune modifies fuel tables to be able to run 100 LL AV gas and reap all the benefits.
    • Level 5 (110 Octane): Kill mode is here!  This tune is developed for 110 Leaded or MS109 fuel (or better).  This tune is an absolute riot and will leave others in the dust!  We throw down a huge 185-190 RWHP (+45-50 RWHP) with this tune at 19-20 PSI of boost, with a wicked timing curve for the big octane fuel.  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/wastegate & injectors.
      • Required Mods: Full exhaust, high flow intake kit and clutch kit.
      • Wastegate Crack Pressure: 2018-21 models shorten rod 5 turns (10-12 PSI).  2017 models w/18 fuel pump shorten rod 7-8 turns (10-12 PSI).
    • Level 6 (E-85): Kill mode squared is running on corn!  This E-85 tune packs as much of a punch, if not more, as the Level 5 tune but must be used with our big 1200cc injectors due to the extra fuel demand of E-85.  This tune is an absolute riot and will leave others in the dust.  We throw down a huge 185-190 RWHP (+45-50 RWHP) with this tune at 19-20 PSI of boost, with a wicked timing curve for the cool burning E-85.  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/wastegate.
      • Required Mods: AA 1200cc Injectors, Full exhaust, high flow intake and clutch kit.
      • Wastegate Crack Pressure: 2018-21 models shorten rod 5 turns (10-12 PSI).  2017 models w/18 fuel pump shorten rod 7-8 turns (10-12 PSI).
  • All our gas tunes are available on our large injectors, so there is no need to switch.  The only reason to go big injector is if you plan on running E-85.  If you don't plan on running E-85, just stick with the factory injectors.
  • 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.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. 
  • Our setup guideline will let you know how to set your weights for stock horsepower to 200 RWHP, 28" - 32" tires, 28-32" paddle tires, different altitudes & more.
