So I'm helping a friend out with a vehicle she owns. She bought the vehicle with the cam already in it. When she bought it, it was pretty stout for what was done. She had a BCM go out and it hasn't been right since. It is a 5.3 with an unknown Stage 3 cam. Also has milled heads with some port and polish work. I was hoping someone could take a look at the file and give some guidance.

Do you have a log or a description of the issues?

I?ve got a log with basic parameters.
Any chance the ECM got reflashed/updated while it was in for the BCM?
