Low boost, higher egt's

[gearhead]

You said that it has @m*m^2 on a 2350? have you tryed comparing the manifold pressure of the ecm to your gauge (if you have anouther gauge) to see if sensor is reading right. Also i have seen turbo speed sensors go bad and cause this. Unplug the turbo speed sensor and take multimeter and ohm it see if it has resistance.Even if ecm shows turbo speed it could be showing calculated value. Also is your turbo compressor inlet temp sensor reading corectly? Five main things if @m*m^2 is done turbo speed sensor, exhaust backpressure, manifold pressure sensor, Turbo or actuator and turbo inlet temp sensor reading wrong.If no @m*m^2 I would need a list a hole page long and still probably not explain it all.
