PID questions.

I'm having trouble trying to get some things to register on the dashboard. I would like to display RWHP, RWTQ, and g-force. I also want to read boost, but it reads around 13 psi at idle, im guessing that ambient pressure.

I did a search on this but most of them discuss accuracy but not how to do it.

How can I display these? What PIDs need to be selected.

Thanks in advance!
