Lastly, don't press on 'identify' anymore since you know your ECU ID (04A60). If it still says corrupted/unsupported, then please reply back here. This is just a tip/summary but please check the instructions for a more detailed procedure. Press on the 'Flash It' button then open/select the tune file from the window that will open. Open the p5flash program you just downloaded. Turn ignition to 'On' (engine shouldn't be idling). Just a tip: Connect your laptop to your truck, using the Tactrix. Turn back on the protections AFTER you have done everything you need to do with our tuning programs. You can add it to the exceptions of the Anti-Virus/Windows Defender. Windows Defender/Anti-Virus software might flag the program as a virus, we recommend temporarily disabling the Anti-Virus/Windows Defender (Real-Time Protection) BEFORE and WHILE using our program. Then, follow the instructions on how to flash/upload a tune. Please note that when you do download this file, don't use the p5flash in the Flash Manager to upload/flash a tune. To update to the latest p5Flash, please download the P5Flash directly from this link: The unsupported/corrupted error usually appears when the p5Flash is not updated.

Am I missing something here? Again, thank you so much for helping me out, can't wait to get this thing working. I had only sent the vehicle info after identifying it with the tactrix cable. I did send the ECU ID, and for some reason got a reply back about the p5flash utility (which was working fine and I hadn't asked about) but no tune files.
