I have unported T-bodies so I didn't run into problems like this. Lol I'm going to check the charging system today after work just to make sure. My dash gauge has seemed to read properly, but I will double check it. I have tried raising P1514 without any luck. I am seriously considering swapping to a cable T-body just so I don't have to go through this ever again.

 

Change REP TPS limit to 100%, disable codes...done!

Lol, I wish I had a better answer. That's a hell of a problem
