Ok efi question.
Things I can do
1. Read the ecm no error codes
2. Flached stock tune off autocal. No errors

What I cant do
1. Load the ridgerunner tune. Keep getting $0537.

I've pulled fuses tried many times. Talked to old owner all they ever had was edge juice with attitude which was unhooked. Am I missing something or am I screwed?
