40 PSI fuel pressure should be ok, but you can back it down to 38 and see if that makes a difference.
White smoke - means you are burning water or coolant.
Grey, Blue smoke - means you are burning oil
Black smoke- indicates too much fuel, which is not being burned.
I'm wondering if you don't have an injector that is sticking.
Or possibly some leaking valves that seal up a bit better when it warms up.
