N14 barometric pressure sensor

Pablo ,Good Info

 

N14 celect plus cpl 2592
Tuned 590 ground hp Pittsburgh tuned. No check engine. Truck isn’t pulling like it should. Have a dd13 engine same weight and the n14 cannot leave it. Ecm wires are good. Fuel is good. Noticed some bubbles inside the tank from the return line nothing crazy. Changed turbo pressure sensor on manifold. No difference. Behind ecm wires on top of the fuel inlet on the cooling plate there’s a sensor. Is that the barometric sensor? 2 bolts. 3 wire sensor. Is that barometric sensor? Could that be failing? Like I said no check engine light. Cleaned out cooling plate. No dirt, air is passing through freely. Check valve is good. The truck starts and runs fine just not feeling the power it supposed to have. Opinions boys?
