I have a 2009 mustang gt 5.2L stroker with a turbo, the fuel system is a fore innovations setup with return regulator that varies the fuel pressure from 40 to 60 psi when the boost comes in. When I purchased the car, it had cels for the frps, there wasn't one on the rail. I bought the adapter and sensor and installed but the cels come back. I know it doesn't affect the performance because the 2 440 pumps are wired straight to the switch, but the engine light drives me crazy. Is there a way to put a resistor in place of the sensor to prevent the code or does this need to be tuned out? Any help would be appreciated.
