Talking 5lbs of boost n bummin out.

97 f250 7.3 4x4 crew cab , found this truck offered a couple grand n now its home. Trying to figure out why she's only pushing around 5lbs of boost. Maybe 7 max. Seems low on power. I read a bit about ebp tube n sensor. Ordered em both new. Should be here in the next day or so. Replaced the boots n clamps. They were just not quite right. The truck doesn't really smoke except a small puff at start up. It runs pretty solid no misses , but I haven't really driven it hard cause I wanted to check out this boost issue. Engine seems to be stock no chip or major mods thatre noticeable. opened up the intake tube to look at the turbo. Doesn't look bad at all. Soooo, I wanna get her runnin right. Can any people point me in the right direction? Any n all help will be greatly appreciated

Check for soot around up pipes. If they are leaking by collector that will be a issue.

Build yourself a boost leak detector and fix the leaks...

No black soot at the up pipes or around any collectors so I'm thinkin the leak detector is gonna be my project for the day.

Re: 5lbs of boost n bummin out.

How are you checking boost? If its a gauge in the cab and you didn't install it, make sure that there isn't any kinks in the tube and that its in a good location to read boost. If you're not driving it hard or putting it under a load, you're not going to see a lot of boost. Sitting in park and revin it with a stock computer and a stock truck you won't ever see much more boost than you. It needs to be under a hard pull to get the boost up. Remember that in stock form these trucks are only boosting at 14psi or so. That being said 5-7psi isn't bad if all you're doing is revin it up and watching a gauge.

Re: 5lbs of boost n bummin out.

Also remember that you're truck is putting less than 200hp to the ground stock. So if you're comparing the lack of power to a newer PS, Duracrap, or Fummins that you may drive for work, its going to feel under powered. Don't want you to waste a lot of time and money only to figure out the truck doesn't make the power you thought it should.

Re: 5lbs of boost n bummin out.

If you are truly only making 7psi of boost driving it, my vote would be either the EBPV is stuck closed, or you have a Fuel restriction

Looking for Blue 40-20-40 seat for OBS. PM me if any known
