The app updates haven’t fixed this ongoing problem. I think the instructions of needing to disconnect the device, and closing, and restarting the app is the issue. Or it’s trying to do all 97 updates at the same time?? IDK, but one update it might need to do first is an update so it can reboot itself while still plugged in, and the app remains open. ### 3/5 — Needs Update For Flex Fuel Relearn *2026-04-21* Using my cheap code reader I saw the alcohol fuel reading for my truck might be incorrect. It would be a great improvement if the PredatorX had the ability to reset it. I give it 3 Stars because it never completes an update. It gets stuck in the 97 update loop. ### 5/5 — 07 corvette *2026-02-16* Works great no issues whatsoever ### 1/5 — Updates Never Complete *2026-02-04* I attempted to update the device at least a dozen times, and it never completes. It always finds 97 updates, and after it finishes downloading it tells you “Notice! In order for updates to complete, please disconnect your device, close the application, plug your device back in, and restart the application.” You do that and it never ever completes. Also if you’re in DEMO mode, and you go to the Store you see a license you can purchase for $29.00 for a Pedal Booster to add more capabilities, but it won’t let you purchase it in Demo mode. So when you leave Demo mode it’s not there. My biggest complaint tho is the updates not working. ### 1/5 — 2014 gmc sierra 1500 5.3 *2025-12-28* I have just received this product and it keeps giving me an update error when trying to install tunes saying please try again or contact support ??? Any help would be nice !!! ### 5/5 — Smooth operation! *2025-12-12* Eveything from the updates to loading the tun went smoothly! I can’t wait for the opportunity to load custom tunes. ### 3/5 — Doesn’t Save Settings *2025-11-23* I made changes to turn off AFM, increase the idle, and did the build, and update. After a test drive I opened the app again, and see the AFM is turned back on, and the idle increase isn’t showing. When settings are changed in the app they should be saved for the next time the app is opened. ### 2/5 — It’s not the best by far *2025-11-03* I have this in my 2015 chevy truck transmission don’t shift correctly has a pulsation on slowing down don’t fill a power difference, and can’t get it to do an update even though every time I get in turn it on it says 97 updates ready to load and then doesn’t load them. Can’t just tpms or anything else for that matter. Definitely not impressed. ### 1/5 — Useless *2025-10-30* Shouldn’t have to take over 4 hours just to update. Other than that any other setting I try to change once a connection is established reads error and to try again another time. Just not worth my time. ### 5/5 — Review 2.0 *2025-05-28* They have updated the software for gm and Chevy i believe tuning for my year and make 17, 1500 lt are tunable and I can disable afm took a couple months with tech support but finally got it all worked out and couldn’t be happier with my purchase… ## Frequently asked questions about PredatorX ### What does the PredatorX app do?
