Hey my turbo boost is to low is not deleted jet and no trouble code sometimes it does up to 30 psi sometimes only up to 20 is a 6.4 do you have an idea what to look for ? Thanks paule
Even with a trailer i hove not more than 25 psi and sometimes if you floor it it dos not go over 10 if you do it little later it goes up to 30 that is what i dont understand and it feels to be really slow sometimes
If the turbo is in good shape and there aren't any leaks or shaft play for either of them I wouldn't be worried. Doubt you have a boost leak.

today i was driving full throttle and the boost came down to 10 psi wich is no fun passing somebody with no power at that moment
i dont have a shop around here the next one is 600 mi away so i have to find it by myself :-(
How many miles are on this truck? That low under WOT and you definitely have a problem. Perhaps you have a clogged DPF creating a lot of back pressure and restricting exhaust flow..?

when i had a dpf it got clogged and did this. it was a constant downboost the more i drove where it sounds like yours is spiking up sometimes...idk...when mine got full it put a hole in the side of the dpf it had so much pressure. the next week it needed a motor...i threw no codes either. maybe try this and someone stop me if im wrong for saying this, take the flange from the down pipe and pull the bolts out and somehow with a ratchet strap maybe pull the dpf away from the downpipe and drive it, that should give the dpf enough heat to think its working and also have enough space for the engine to breath. i just came up with this so it may not even work...i would try it if it were mine tho...it will be blowing black smoke from under the cab but shouldnt hurt anything

If there is a way to do it like you've said that's what he need to do, somehow run the truck without the DPF, but it's only likely to be the DPF if the miles are up there. How many miles were on yours when it clogged?

Do you do alot of driving under 80kph? Has it ever given yôu the "drive to clean exhaust message"?

Pulling the dpf off like that without a tuner will put the truck into regen. That means you will have raw fuel puring out the exhaust and then down the truck and road.
How much I do not know.
What you really need to do is take it in for a diagnostics.
They can command the turbos and check the pressures and the DPF as well.
That would be the best way to determine the issue.
Just my 2 cents.
