    I have been working for years to quiet down my 7.3. Is your friend running synthetic motor oil? I found synthetic makes the biggest difference of all. I also run Hot Shot Secret. It's an injector cleaner that actually cleans the moving components of the injectors and not just the tips.

    Do you still have your hood blanket?

    Have you both been to Ford for the CPS recall. The new one seemed to quiet down my engine even further. It all has to do with engine timing.

    I have done some interior work to my truck and now I can cruise down the highway and basically hear nothing but the turbo. I don't even have to shut my engine off at drive thru windows.

    we all run the same fuel and oil ,the only recall was for the crank sensor unit .maybe a programmer will help ?been thinking of getting 1 anyway .the noise is not a problem its just the thought of being that noticeable

    Programmers, under certain setting, will advance the timing and actually increase combustion noise.

    Perhaps you are getting air into the fuel lines. Air bubbles will cause major injector noise.
