Doing a black box swap and only pcm i have is a 09354896 with a 9365637 OS. Cant seem to find a 80e tune with the proper OS in the repository. have the 5.7 data i need unless someone has a complete tune i can swap with the proper OS. This is my first swap with one of these and didn't have time to source a 411 pcm as this guy is in a hurry. Any direction would be appreciated thanks.
The Pcm is from a 99 chevy 4wd with a 4l60e
