Powerstroke Greenhorn here

Hey All,
I recently decided to park my cummins and get workin on my powerstroke again. I know a whole hell of a lot more about the cummins than I do about the powerstroke so I am looking for some guidance. I have a 94.5 F-350, 5 speed, single cab, flatbed, 285,xxx, banks powerpack, 4" MBRP. My father bought it brand new in 95 for his concrete company and it was my first truck when I was 16. At some point I jumped on the Cummins bandwagon and that was a lot of fun (and money) but I have been missing the old hog. I remember when I parked the powerstroke I had a few questions. First, the banks turbo housing f***ed with the EBV. How hard/expensive is it to delete the EBV. I have all kinds of wire trying to hold it open but im not sure if its working. 2nd, it peaks at 15lbs of boost. Is this because of the ebv being open or does this number sound normal. I am used to seeing a lot more boost in my dodge so i find it concerning

Thanks,
Kelly

The EBV isn't a big issue unless it sticks closed or something, and you'll know it - you will have a gutless wonder. As long as it's open and staying open, no real need to mess with it more.

15psi sounds reasonable for a stock truck. Maybe a bit low. Check for intake & exhaust leaks. But with nearly 300k miles, if it's got stock injectors, that's probably fine.

My e99 puts out about a max of 17 I have seen so far so I wouldn't be worried about the boost. To delete the ebv isn't too bad of a job from what I've read but it's not a necessity, I would keep it in place if you live some where it gets cold.

15 psi on stock settings is reasonable with those miles. If you're only hitting 15 psi in highest setting than you got some leaks. Check your intake boots for cracks or tears and inspect uppipes for exhaust leaks (soot streaks on pipes or soot on firewalls). Also how does the turbo wheel look?

15 psi is not reasonable in my opinion My 94 has 290k in the clock and I can hit 23 psi easily if I run it up to yellow line on tach. I would say if you can't do that you have an preturbo exhaust leak somewhere in the exhaust or turbo to intake plenum leak.

I saw those numbers on my Cali model with canned tunes, it has bigger injectors, how do you see those numbers?

Before I did injectors, exhaust and a tune the highest my boost gauge would see was 10. now it will run up past 30 if I let it.

I'm taking that reading off a boost gauge t-d into a map line my 97 with fresh motor will 25. Like I said I have to take it all the way to the yellow line in the tach to get there though
