Default Fuel Pressure Regulator

I have a 2004 Cherokee, with the 4.0, which I am in process of turbocharging. The OEM F.P. regulator does not have a manifold port to automatically adjust F.P. based on manifold pressure (boost), like most boosted engines. What have others done? I can change the regulator to one which has a manifold port. Do tuners just over compensate the fuel curve at boosted MAP levels?

IMO, ask the turbo manufacturer.
