I know she looks a little dirty, but I am actually cleaning up the engine bay now. Just taking a quick break!

Disregard the question. I just got a pretty good crash course on it.

It is not safe with a PFC to just plug it in with a full bolt-on car and let her rip -- this is safe with the stock ecu at 10 psi.

Was there ever consensus between these two conflicting posts? It sounds like there is no way of knowing for sure without accurate AFR data from the particular car?
