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 wish I had the equipment to test these
Will a ODBII test this if not I have no clue where to begin very much a novice here.
I'm Just not scared to turn a wrench lol

 

Before you start buying stuff or getting numbers, take it for a drive and floor it and see what you get for boost

 

there's no load sitting in the driveway so there's no boost.

 

Took it out as suggested and got on it boost between 20&25 psi and I did notice some slight cracking in the
Charge air color hose / turbo boost hose. Replacing both this week.
Thank you for the suggestion .

 

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
