I do see black smoke coming from my exhaust, but mostly only when it's cold or when I take off from a start (particularly when I floor it, such as getting on the freeway). But most old 617s that I see driving around have some form of minimal smoke coming out of their exhaust pipes.
I guess I won't worry about the Overboost Protection Valve right now. How do you tell when your wastegate isn't working correctly?
