If your running around 11lbs, you should up the fuel pressure to about 34 psi. For every lb of boost, a lb of fuel pressure. 3000 is right where you should be at full boost and if you are leaning out because of fuel pressure, that would probably make it bog. But I couldn't see it doing it that much. Check it any way. Did you check all of your piping and vacuum lines?
