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 Ranger 570. If you are looking to tune two vehicles with your Powervision 3 (Not applicable to PVCX or PV4) please read this page thoroughly before proceeding. If tuning two vehicles with your PV4, the app will prompt you to purchase a License for the additional vehicle. We are highly experienced in tuning the Ranger 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 Ranger.  Each tune is built specifically for your Powervision allowing us to change the tire size or fan temp 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 (PV3 only in video).

Features:

• Big horsepower & speed gains!  The factory 570 Ranger is just like the RZR and ACE 570 is very limited from the factory.  The 45hp motor is capable of much more and we are here to deliver!  The factory limits you with torque limits to only allow so much horsepower to be made, very low 50mph speed limits, and a very timid rev limit.  We unlock everything in this motor to gain another 5-7 horsepower.  You'll notice MUCH quicker throttle response and power delivery especially in high gear.
• 100% Throttle in high and low gear, throttle by wire limiters disabled (on those models with TBW)
• AA's wicked timing and fuel curve for either 87 or 91 octane
• More mid range fuel for increased mid range power and response and a better fuel curve all around
• Cooler running motor with the fan temps decreased to 195 on / 185 off
• Factory 50 MPH high speed limit removed, 24mph low speed limit removed
• See speeds around 60mph in high gear
• 2 foot limits disabled (brake/gas at the same time)
• Optional seatbelt limiter disabled
• Rev limit raised to a safe 8000 RPM
• Removed torque limits that keep the motor from revving higher
• Choose between different tunes for 87 octane or 91 octane
  • Level 1: This tune is the most common and is meant for the factory exhaust system, and no other major engine modifications.  When properly clutched, this tune is capable of 52-53+hp on 91 octane fuel.  With the 87 octane timing curve, you would see around 50 horsepower.  Peak power is made between 7500-7700rpm, so clutching is highly recommended for best performance.  
  • Level 2: This tune has all the features of the level 1 tune, but the fueling is designed for an exhaust system.  Gains would depend on the exhaust that you are using, but normally would show another 3-5 horsepower.
  • Level 4: This tune has all the features of the Level 2 tune but with fueling and timing for a big bore kit.
• Looking for a custom race fuel tune? We also have those available upon request. They offer a timing curve set up for race fuel.
• Wondering why go with our tune(s) over the DynoJet tunes? We go the extra mile to make sure everything is gained, and have a few extra tricks up our sleeve because we test in the real world. Other maps take their time to hit peak timing numbers which really hurts performance. Our map gets you into peak timing quicker, so max power seems more instant. We also have a great fuel curve that is designed to go with our timing curve, and offers better fueling for more power at WOT.  We also do some work with torque limiters as in the dirt we saw throttle closures when spinning the tires. Our map fixes that issue giving you 100% locked power delivery.  We also do the easy things like up the speed limiter to where you will never hit, disable 2 foot limiters, and disable seat belt limiters.
• We always recommend tuning with clutching for the biggest performance gains.
• Tunes are said to "Ship for free" but will actually be e-mailed over to you within 24 hours of placing your order (Weekdays only).
• Not good with computers? No problem. Simply send us your Powervision (PVCX/PV3 only) and we'll install the tunes for $25 which includes the shipping back to you.
• PV3 Users to send PV_INFO: To get your PV_INFO number simply plug your Powervision into your computer (No software is needed and this will work on an Mac or Windows computer) using the supplied mini USB cord. Wait for the POWERVISION device to pop up as a drive. Once it pops up, open the folder for this device.  Inside the folder for the POWERVISION you will see a PV_INFO file which will need to be attached into an e-mail and sent to aftermarketassassins@gmail.com
• PV4 Users to send PV_INFO: With your PV4 connected and app open on your phone, Hit "Scan" to search for your connected PV4.  Tap on the "Dynojet PV4".  Your Connected Vehicle should show your VIN and ECU information. (Verify this information matches your vehicle) Select the share icon next to "Connected Vehicle".  Select your e-mail app (Gmail, Yahoo, etc.). This will open a new e-mail with the attached PV4/ECU information.  In the "To" line, fill in with   aftermarketassassins@gmail.com  .  In the "Subject" line, fill in with your name & invoice #.  Please note that if your e-mail associated with your PV4 account is different than the e-mail you are using to send the info, please make special note of this and attach the e-mail associated with your PV4 account.  Send the e-mail and await further instructions when we send your tune file(s).
• PV3 Users to download tune(s): Simply download the tunes from the e-mail we send and find where they are located (usually the DOWNLOADS folder). Copy the tune files by highlighting them and plug your Powervision into your computer using the supplied mini USB cable. Wait for the POWERVISION to connect and open the POWERVISION drive. Then simply copy the downloaded AA tunes into the main POWERVISION folder with the rest of your supplied DynoJet tunes.
• PV4 Users to download tune(s):  Open the Power Vision 4 app on your phone. If you currently have the app open when we send the tune(s), you will need to completely close out of the app and re-open it.  At the top should be a "There are shared invitations" notification. Tap on this.  Tap on "Accept" to accept the tune(s) from Aftermarket Assassins.  Tap on "Tunes".  The new tune(s) will now be listed at the top under "My Tunes".

Click "Yes" if you wish to purchase and redeem a License token for your vehicle.
• **Tunes are password protected so you will not be able to open or view them in the C3 tuning software**.  This keeps our tunes protected from copying, and gives us a good reason to keep putting in the time to make the best tunes out there!
