6.0 dropping boost

[DEEZUZ]

Got one that's throwing me for a loop.

06. Manual. Egr gone.

The customer installed new Ford map, new ebp sensor(Dorman).

Rowing through gears you lose boost. It just drops.

I found the ebp tube was plugged. Blew it out. It ran great. Few weeks go by, it's back same Thing.

I find his ebp koeo is 6psi. Install new sensor. Now ebp is OK, I won't say perfect.

Same Thing. I put a new garret on it 2 years ago, don't think that's the issue.

I want to say it even over boosts as I've seen 29.9 psi on map

All over the place. Will get specifics tomorrow but it will drop to 14.99 sometimes.

My guess is you’ve possibly got a boost leak opening up, or an exhaust leak. What’s all done to the truck? Tuned, egr, exhaust?

13.9 ebp cold with shit sensor. 14.5 with new oe sensor.

Cold the vgt shoots to 84%, after 1 min now 75%.

Cold idle ebp 17.2

Vgt drops to 14.99 during event and the exhaust sounds like machine gun, popping and such.

New oe sensor the ebp hot koeo was 20 psi. Tearing into harness now but this hasta be pcm issue.

No egr, he claims no tune but the cooler is gone but it nevers throws egr codes like 1408. It's a manual straight exhaust... The truck acts like a plugged cat

This happens too sometimes.

Thanks brother.

Concern is I've got 20 psi charging this cooler and it's slightly bigger than a pinhole leak. Gotta fix what's broken first..
