    I thought that my 04 dulley durmax was loosing power, so I took it the the dealer, they checked the computer and everything was fine. they called and sais that the last test was a intake pressure test and asked if I wanted to do the test for $100 or something like that. I said yes. They found a few leaks at the hose clamps. I now have a noticeable power increase.

    Probably loose clamps at the intercooler.
