So I went down a multi forum egr/ throttle plate rabbit hole last night, which brings me to this:
I currently have my throttle plate removed, my egr open and unplugged and installed in the intake.
Much like many other people my boost only hits low 20s. I dont know what it was hitting pre " delete " as I wasnt up on my monitoring game back then.
Don't delete the EGR valve and don't unplug it. But delete the EGR cooler. What advantage do you expect from a valve delete / plate delete?
The EGR cooler is the cause of many problems.
Late 04 stock tuned, egr valve in place and plugged in.
EGR cooler cooler not in place.
Throttle plate removed using stock 05 intake elbow.
Hitting max 30.3 boost using BD xmonitor that i installed way back in 04.
Starting to think my gauge isnt accurate based on the low boost #'s you guys are reporting?
Mine has been this way for years now. My main reason was to keep the egr from sooting up and sticking. It felt like I was always swapping the clean spare in. Havent had an issue in years.
30 lbs of boost is alot ( compared to mine) I'm not sure what a " stock" 6.0 is supposed to make. It seems like everyone is different.
Hartwig- any reasons to put it all back? With the coolant filter the egr cooler should last for a while.
joe blow - what's up with the spool? I've heard about them. No first hand experience.

It is a billet aluminum spool that utilizes the same OEM o-rings, and replaces the valve. It basically stops the flow of gases back into my manifold. You can find them on ebay but the US manufacturer is no longer on there. I am sure you can find one if you looked.
Stock benchmark for you. My truck is 100% stock with EGR 100% intact (BPD cooler) and original late 06 programming. Full pedal pulling a trailer uphill I can get about 25-26psi of boost. Maybe 27 when its colder outside. Reading with an Edge CTS3. Harder to get those numbers without a load as the truck will rev out and shift. I can usually get it to about 23-24.
No boost leaks that I can see. All boots and intercooler are dry, 03/04 metal cold-side pipe. No up-pipe or exhaust manifold leaks.
My old 05 (also stock) behaved pretty much the same way.

I'd say we are about the same
Have a freeway on ramp next town over that has a decent uphill and the fwy is uphill too - at least a mile of it. I use Torque Pro and my real time gauges are the ones that capture min/max - pedal to the metal onto the fwy and I see pretty consistent 27.3 or lowest is high 26s for boost (no load/trailer/ empty bed). Have a BPD (like) EGR cooler from BD Diesel, everything is stock including the original programming. I will add that this onramp/fwy is at about 1000' elevation...
