slow boost till 7 pounds then builds up normal

[harman99stroker]

i have a 99 7.3 had it for awhile just the normal chip intake pipes that stuff just replaced the boost tube that comes up in front of the hpop and the sensor the tube had a hole truck ran good for over a week ran great last night drove it today and from a light cruise in any gear its a 6spd if your at like no boost and u peg it to the floor its takeing like 5 or 6 seconds to get up to like 5-7 pounds of boost its like its fighting to not build boost once it hits that much it puts u in the seat just like it always did and it u shift fast and keep it ripping its fine.....does anyone have a clue why its fighting the low boost info would be very helpful thank you ....there is no abnormal noises like whoosing air or anything

How long has it been since you changed your fuel filter?

[Turbostang500]

if the fuel system is ok I would look at up-pipe leaks or maybe the wastegate not closing all the way.

So it started all the sudden. Cause on my truck if I'm at a low RPM, say 1300, and peg it, its gonna take 5 or so seconds before it gets going.

Standard boost leak?

[harman99stroker]

brand new oil change and fuel filter change and no leaks i found whats caused the problem just dont know why....the tube that runs from the right manifold up in front of the hpop was bad so i replaced it and the eb sensor now the truck ran fine like that for nine day it fix a problem i was having holding low boost anything under 5 psi it would drop to 0 and u would hear a woosshhing sound and lose alot of power but after 9 days this new problem started i unpluged the sensor unhooked both batterys for a min or so and fire it back up and it run perfect again so piss on it i got to put a 4 inch down pipe on im either going to get a new pedastool with no ebpv in it or just gut the one that thats in it and get the eb sensor elimantor from dfuser diesel and be done with it ...the truck gets to live in a warm garage for the most part i dont need a back pressure valve

[kanuck15]

So your back pressure valve is shutting on you?

[harman99stroker]

it doesnt sound like it is ...but not really sure all i know is truck runs right when its unplugged havnt had time to look at it to be what is really going on just yet
