'06 with power loss looking for answers...

I have a 2006 CC 2500HD that seems to lost half its power. I had it programmed with my PPE standard at level 3 and noticed one day that my DMAX was a lot weaker then it was 2 months ago. I now get more black smoke then I remember getting too.

From zero to a third throttle it seems fine. If I go over a third throttle I get a ton of black smoke and little if any added power. Just more smoke. I took the level 3 off, went back stock and this thing is so weak I'm not even sure it'd pull a load much less pass a car.

After putting it back stock I got the following codes on the way home from work: P0101 and P0299. The air filter is maybe a year old. I cleaned the MAF sensor before going back stock with MAF cleaner. I do have the EGTs blocked and 4" (turbo back) exhaust on her. Not sure if either of those would throw those codes or not. The fuel filter still has 75% (per the DIC) life left on it. I did a quick once over on the intercooler boots and they looked fine.

The only thing other then the power that I've noticed about the truck is that the turbo doesn't seem to whistle as loud as it used to. I'm not sure if I'm getting used to it or if something is going wrong with it.

I would greatly appreciate any suggestions on what to look for or test so that I may get my power back.

First 2 things I would look into are the airfilter and fuel filter. A year is a long time to have an air filter IMO.

When you blocked the EGR did you disable the computer or install a finger stick?

+1 on the fuel filter, clogged filters can cause all kinds of troubles.

Well I went ahead and replaced the air filter tonight after work and boy am I glad I did!

Check out what I found:









Apparently a mouse had made a nest in my airbox. That gray fabric crap is from a vehicle cover I had over my '88 Chevy C1500. Looks like my truck shouldn't have even run it was clogged so bad. I think my engine was about ready to suck my air filter down and eat it for lunch.
