Curious if the 9381344 OS has ever had an XDF made for it yet. I tried google with no luck. I ordered a custom tuned pcm, and it came with that OS unfortunately. I didn't think to specify what OS I wanted them to use, but I'd like to be able to change tire size, and I'd rather not have to buy HP tuners. I was able to open it with universal patcher, but I'd rather be able to open it up in tunerpro.
