ok, here's a caveat to the question. Under boost, if fuel pressure was constant, did not rise w/ boost,, say 3 at bar of fuel pressure, under boost would you actually flow less fuel because of the increased manifold pressure. So at 4bar under 1 bar of boost,, you would actually only flow 3 bar's worth of pressure though the injectors, again given that the fuel pressure did not rise.
