  • Stock X3 RR on our dyno was 162.2 rwhp
  • Our level 1 tune is designed for a completely stock X3 RR on 91 octane or better.  This tune runs an average of 19-19.5 PSI of boost and is a very safe tune to run on even 91 oxy/ethanol fuel.  Gains are right around 10-12 hp to the wheels.  We found many competitors only offer a max pump gas tune and that simply does not work as well without having a good 91 non ethanol or 93 octane fuel.  If you run into this, your safety circuits will pull timing based on engine knock and can even go into a partial limp mode dropping you down to below stock boost levels. This is a great tune to have loaded on the tuner for such event that you get bad fuel, are just looking for a simple tune with limits removed and some great power gains. It still rips, but won't push the limits as much.  It works well with a 100% factory machine or with an exhaust. The stock waste gate spring pressure works best with this tune.
  • Our level 2 tune is again designed for 91-93 octane and is a max tune on the stock exhaust. This tune is absolutely nuts for being able to run on a bone stock X3 RR making 178-179 rwhp.  Boost comes on hard and keeps pulling like an animal.  Peak boost is around 22-23psi, and settles down to roughly 20-21psi.  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. You simply can't find a more powerful tune on a stock X3 RR. This tune will work even better with an exhaust like our 3" full system. Your waste gate rod should be shortened 2 turns from the factory position with a crack pressure of 9-10psi.  Stock clutching is okay, however look for our full clutch kit coming soon to better transfer more hp to the wheels.  Our blow off valve kit is recommended.
  • Our level 3 tune puts the hammer down on 91-93 octane.  Like our level 2, this tune simply rips on pump gas but requires a full exhaust like our 3" system 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 leave some power on the table). It will peak around 22.5-23.5psi and sustain around 20.5-21.5psi.... half a pound of boost higher than level 2.  This is a big 22-23hp gain over factory, making 184-185hp on our dyno.  Your waste gate rod should be shortened 2 turns from the factory position with a crack pressure of 9-10psi. Our blow off valve kit is recommended with this tune.
  • Level 4 - Beast mode - 200 RWHP!  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 other race fuel with the tune to get 100 octane output would work great, just keep in mind leaded fuels can take out o2 sensors when running leaded fuel consistently.  Now for the fun part.... this tune is INSANE and brings your X3 RR to a new level at 200 rear wheel hp on our dyno. This tune gains 37-38rwhp on pushes the boost level to 25-26psi peak, then settles to 23-24psi. Keep in mind the powervision boost only reads to 22-23psi (depending on your altitude) so it will max 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.  A free flowing exhaust like our 3" system is highly recommended for proper power and to sustain power.  Stock clutching will work, but our clutch kit is also highly recommended.  Your waste gate rod should be shortened 6 turns from the factory position with a crack pressure of 12-13psi  Our blow off valve kit is necessary when running this tune to prevent turbocharger damage.
  • Level 4AV is the 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 the oxygenation and other characteristics.  Running a tune not meant for this fuel can make it act lean and therefor 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 Kill mode is on the horizon, check back for more info.
  • Level 6 Kill mode squared running on corn (E85) is on the horizon, check back for more info
  • 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.
  • To prevent turbocharger damage, we would recommend our blow off valve kit on tune 2 or higher. Level 4 and higher the blow off valve is necessary.  Running this much boost, turbo surge can be a real problem when in/out of the throttle. 
  • Get ready to hang on, your X3 RR is about to transform!
