You want to go to here
and get a Dual Relief Valve.
This mechanical device is intended to be installed between the MAP sensor and the intake manifold on all Fords 7.3L Turbo Diesel. This device allows any boost pressures above 22PSI to be released so that the SES light is not set and the MAP sensor does not send signal to the PCM to go in to a defueling mode, if you are running high boost, typically found on aftermarket High Performance chips and programs.
