boost pressure????

I have 96 f250 with the 7.3,with an automatic tranny. I just put a set of gauges on it and my boost is about 10lbs. Is that normal or is there a problem? I do have a 6 position bullydog chip on it. Its the same on 30 or 50hp. Thanks for any help!

Re: boost pressure????

Is that at WOT (foot to the floor) or is that like "well I kinda was going from a stop and goosed it for half a second?"

Yep if thats at WOT then you got a problem. And I would ditch the bully dog. IMO.

Re: boost pressure????

I lost boost and all pulling power last week, max boost was 9 or 10.
My fuel pump had 50 psi at idle but low on hard pull. I changed the fuel pump and 15 boost and all the power I need from my stock mason dump

Re: boost pressure????

Depending on how old the bully dog chip is , you may be able to get it reburned with better tunes on it.

Bullydog is crap on almost all diesels. They are hard on trans and there hp numbers are weak. With a custom tuned chip you will get better mpgs, power, settings, and reliability. Also with bullydog you can not run bigger injectors or hpops correctly.

Once had a signature that had some bad ass stuff on it. Now its back to crap.
