Default fuel pressure regulator.

My corvette has a TPIS intake system. which means no cold start injector; I have an adjustable fuel pressure regulator; Running 47lb. but the problem oi if is at full pressure the minute you start the engine consequently running really rich until the engine warms up.. I have heard later model corvettes have a adjustable fuel regulate that actually regulates.. . the pressure at idle than builds up as required which can be installed ans splices into a vacuum hose to regulate pressure. can anyone give me any info on this? Thank you
