If you are looking for the most badass custom tunes that are easily loaded to your X3 RR 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 AA's 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 that will show. AA's 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.
The 2021 X3 RR is quick out of the box, but why stop there? The potential for this X3 RR is so much more. The intake, turbocharger and intercooler upgrades on this model make it easy to crank up the horsepower, and still maintain low intake temps. We are very impressed by what this UTV can do out of the gate with very few modifications. The factory seemed to make the boost come on very lazy, while it peaks out nicely around 18-18.5psi (at our location, 1000ft altitude) it takes a bit to get there. Our tuning makes peak boost come on much quicker. The factory also makes boost fall off a cliff over 8000 RPM. AA's tunes will maintain boost much better at higher RPM's to hold the power, and allow you to clutch at a higher RPM where these motors like to run. Read below for even more information on AA's tunes.
Huge 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 of the powervision 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 air/fuel ratios
Cold start fix! These are very lean when in warm up tables and run like crap. We make them start, idle, and take off much better when cold.
Boost tables properly modified for the fuel & modifications along with lightning quick turbo spool
Timing tables modified for best power/punch per tune
Safety parameters to protect your motor and turbocharger are still in place
Speed limiters removed
2 foot limiters removed
Start in any gear
Coolant and intercooler fan temps lowered
Rev limit raised from 8300 to a safe 8800 RPM
Powervision flash tuner reprograms your ECU in roughly 8-10 minutes per flash
Easily installs by plugging into your diagnostic port (located in your fuse box panel)
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
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 wastegate 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 wastegate 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 wastegate 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 wastegate 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!
