Alright, I am trying to troubleshoot a drivability issue on a stock 2013.
Low power, big time lag and fuel knock. I have followed the all-data directions and tested stuff but the pressure sensors have me hung up.
The exhaust pressure sensor does not match the other three but only by about 0.5 psi.
The other two differ by .1.
What is the acceptable range for these? Need help!!!!!

Is this a tuned truck?
Nope, stock as can be.

Any codes?
No codes.
Data logged and graphed the sensor and it showed some spikes but attributed that to the cylinders firing.
Exhaust brake was wonky the last time I drove it to.
Have not driven in over a week.

Can you provide any log files or outline the data points for these PIDs
Rail Pressure
RPM
Boost Pressure
MAP
Injector Duty Cycle
Accelerator Pedal Position
Last time I drove it, the rail pressure was in spec at idle but lagged by at least 1000 while accelerating and over ran by more than that when I let off.
I am leaning toward a failing FCA or turbo but trying to do my due diligence.
The truck has 36000 on it while the short only has about 10000~12000 on it.

Found my last data log. I also graphed some of the data and had converted the bar pressure readings to psi for the graphs while also graphing vs throttle position. I hope you guys can help. If not then i go to the dealer mode and start throwing parts.

I didn't see how many miles are on the truck.
That might help.
Check the lift pump.
