I have a 2007 peterbilt with a c-15 acert. The problem that I am having is I can't get over 30psi in boost. It might get up to 40psi sometimes but it be right at 30psi. I changed the cac witch did have a crack in it but at one point I was getting around 43psi. And I haves hooked the computer up to my ECM but it won't communicate to it. Can any one help me with this. Ohh I also put a boost sensor on it to still nothing

Make sure to check the inline filter on the boost gauge line at the head. These motors produce a lot of carbon deposits in the head with the valve over lapping and that filter plugs up giving false readings.

For me... I had the same problem... For me it was the fuel transfer pump. I checked the fuel pressure. It was low... Installed new Fuel Pump... 40ish boost twin turbos... Hope this helps.
This site has helped me tremendously.
Thanks to all that respond here -
Also, Like someone else said... I had a charged air cooler leak... or intercooler leak...
Not enough air volume.
Some say get the 1500.00 one it's the best... I went with the 750.00 one. To me same thing... NEW is new -
