I bought a 2015 mustang GT with a roush phase 2 supercharger. The car came with an SCT X4 with 3 custom tunes on it. I plugged it and the device needed a firmware update and said I needed to return the car to the stock tune. So I did. NOW, I don't know which tune was loaded on the car and am very fearful of damaging it by starting it up. I had taken some pictures of some screens prior to returning the car to stock. One says current flash version on it with "8YFJQ6B" I tried loading the last one of the tunes on the list "REV1" thinking the last one on the list would be the most recent one. But it gave me a failed error at the end of programming. So I flashed back to stock. Then tried R1B and it loaded fine. I'm just fearful of starting the car now. Is there anyway to see when these tunes were created so I would know what the last one added to the device is? Or am I safe since the 8YFJQ6B matches on the screen for "Currrent Flash". I'm brand new to this and in over my head.

This is the one I loaded after the return to factory. If it matches that Current Flash screenshot above which I took prior to returning to stock, will I be fine since the codes match? I have not idea for certain which tune was on the car when I bought it.

HI, do you have the device updater by any chance? Do you know how to get a .bef from the device by any chance? how many times did you flash the vehicle?
