Low turbo boost (puzzled)
I have a 2006 F250 and I just replaced egr cooler, oil cooler truck started fine after all back together but had no boost pulled turbo to clean and it was rough to say the least so I had it rebuilt by a reputable shop here in town.
Noticed there was a lot of back pressure so I took care of catalytic converter as well.
After re installing turbo I still only get 5-10 pounds of boost at best when I accelerate with truck sitting there not driving.
I checked and replaced map sensor hose and check EBP sensor and tube all good. No codes and still no boost SMH confused.
I don't have any test equipment so here I sit stumped.
If you have any ideas please let me know.

It's normal to not make much boost in the driveway. Accelerating at higher rpm or better yet up a hill is a good way to check max boost.
Check map, baro, and EBP with the key on engine off, idling in park with a/c off, and revved to 2,500 rpm. Those 9 numbers will help us to get an idea of what's happening.

I am very grateful for all the help and input you guys provide. I'm very much a novice working in Diesel engines and at the present time as a newly single dad not in the position to afford the shop mechanic prices unless absolutely necessary. So I want to personally thank you guys for all the info you provide here, without it my truck would still be parked.
Once again thank you👍👍👍👍

You can get a Scanguage for around $112 from Advance Auto, use the TRT30 code at check out. If you don't have a way to monitor data live it's a good tool.
Download ForScan for free to a laptop, then get an el cheapo ELM327 obdII wireless reader.
ForScan is a pretty cool tool for looking at a lot of different parameter and even does some basic things like injector buzz test.
This sight is an awesome resource for all things 6.0 or SuperDuty
