Post MAP, EBP, and Baro values at KOEO and at idle.

Make sure that the MAP sensor hose is not plugged up and does not have any leaks.
Make sure the nipple on the intake manifold that the MAP hose connects to is not plugged up.
Make sure the EBP sensor is not fouled with carbon.
Makes sure the metal EBP sensor tube that connects to the exhaust manifold is not plugged up with carbon.
Look for signs of CAC leaks at the clamped ends of the boots and look for signs of the boots "splitting".

 

I’ve tried all these things , and thanks so much

 

You haven't tried posting your MAP, Baro, and EBP values .................

Asking for help without providing us data is a recipe for expensive guessing.

We also need the PCM to be scanned for codes with a GOOD code reader. Troubleshooting is rarely a one post question and a one post answer.

 

My apologies Boss, my scanner doesn’t scan all the codes as you mentioned.. for some odd reason this truck rarely throws check engine lights.. but the dealership scanner can read all the hidden codes that the truck has.. I usually have to bring it to the dealership so they can scan the codes and just haven’t had the time.. I’m sure that’s it’s throwing a certain code just haven’t had access to one ..

I’ve changed the map sensor and hose , New EBP sensor and cleaned out the hose changed boots and clamps.. even changed the EGR .. it’s weird because sometime out of nowhere it’ll just start running fine and I’d kno because the veins would just silence and it’ll run like it should

 

ForScan download (Full version to a Windows laptop or Lite version to a smartphone). $6
OBDII adapter - which one depends on your device. Many people say that the VLinker FS works well.
The more expensive VLinker MX+ works VERY well (for $140 though).
ForScan is a pro level scan tool - retrieves PCM data AND reads codes thoroughly.
The full version on a Windows laptop can command actuators - like the turbo's VGT actuator.

Thanks so much I think this is exactly what I need , going to order right now !

 

Wiring to the VGT and EBP sensor? Those pigtails are both common failures.

My EBP pigtail looked fine on the outside, but when I would move the wire loom the reading on the scanner would change. POS aftermarket one the previous owner had installed.
