stock boost psi?

[dieseldan2005]

What are you guys with 7.3's running for boost when your in stock mode or just don't have a chip or tuner at 55mph? I changed out my ebp sensor about 3 weeks ago and after that i would hold around 2-3psi on the gauge. Now its back to around 1psi. Nothing changed except it warmed up slightly outside, but thats it. When i replaced that sensor i also had a code for "no boost psi" and something with my map sensor. I got rid of my edge so i can't check codes right now. Any ideas guys?

right now at fifty five i am reading no boost. if i get on it stock i can hit around 10 psi that will change real soon!!! But 75 i will run about 4 pounds

Ok well that sounds like what mine is reading then. I can also get it up to around 10 psi when i get on it. I test drove a 99 psd this weekend and it had crappy banks gauges on it, that boost gauge would shoot right up to 20psi if i got on it. So is was like wtf. Is this gauge messed up or is my truck messed up? That 99 didn't feel like it was chipped or anything.

if it didnt seem really spunky i would say maybe the gauge tubing might be pinched. i would hit 15 psi with my boost gauge before i cut the smashed ends on it and replaced so it was a good flow for the psi tube and re did the ends

when I put mine in the stock setting it pegs about 18psi at WOT.... it is just a plain a$$ turd in the stock setting!!!

about 55 in OD it is usually 3-4 psi and 55 out of OD it is usually 5-6 psi.... and I have 3.73's in the rear...

So it sounds like they kinda vary a little. I am used to my truck being in stock mode now Jim. I know what you mean, stock sucks. I just don't have the extra 4 hundo for dp tunes right now. So i take it your happy with your DP tunes? Thanks for the info Jim.

yea I hate the stock setting! LMAO!!

yea a normal PSD is suppose to get about 15-18 psi at WOT....


I am SOOOOOOO happy! I get a grin on my face every morning I get in it! LOL

mine is a stock 96er. at 55mph i get 4psi.

16-17 seems to be average for stock programmed trucks. Add a load and that number goes up a few psi!

Driving at 55 I was registering 2-3 psi with the stock turbo.

i gotta wait a while for my dp tunes. So do you think i might have a map sensor issue since i'm not boosting to 15-18psi? I gave it almost wot the other day and got about 11psi out of it. Marc said that when i first pulled the codes for ebp sensor and for the map sensor that a bad ebp sensor could cause the map to trigger a code.
