Replace your damaged or malfunctioning rail pressure sensor with this new one from DHD. These sensors are not OE Bosch however they have the same fit, function and scaling as OEM.
If you have a rough idle, poor fuel economy, and low power, this may be the fix.
This particular sensor is popular among high performance builders as a replacement for their LLY or LBZ OE sensor. Unlike the LLY/LBZ sensor, the 700-12651990 will report readings up to 31,000psi. Your truck will need the tune edited to rescale the pressure readings.
