I have been considering going with a turbo and I got to thinking. (always dangerous). 

I set my fuel pressure regulator with the engine off and at ambient atmos pressure (55 ft so pretty close to sea level), then the regulator reduces the pressure when the engine is running at a lower manifold pressure than ambient.

My question to those who know is if I boosted the engine to say 38-40 inches, will the regulator increase the fuel pressure accordingly?  The regulator is Aeroquipt.
