I’ve recently deleted and tuned my 2016 ram 2500 and after about a week of running the out of the box tunes that came with the programmer I reached out to a custom tuning company and got a custom to for my truck the truck.

It ran well for about a week then I got an invalid SD card error and I reformatted the SD card.

The truck ran well for about another week until the error came back I then purchase a new SD card and reformatted it with the tunes I received from the tuner.

This is a very reputable tuner that did the tunes for me any insight as to my the warp race me tuner keeps having this issue?
