    Forum member @brandonjansen has had his removed on his 2012 for some time. I tune his truck and I've never heard of any issue from him.

    I guess things have changed somehow. If we did it in a 3rd gen, there were issues. Maybe I'm just too out of date. Hell I was one of the pioneers of the EGR and DPF removal. Did BETA for H & S.

    Discuss. As I mentioned, diesels do not inherently pull a vacuum as they do not have a throttle plate. A topic covered at lengths on that forum.

    The manifold sees atmospheric pressure until the turbo creates positive pressure.

    Yes correct

    But with the restriction of the air filter the turbo creates a vacuum on the compressor inlet "between air filter and turbocharger where the silencer ring goes


    Probably working on something

    taking out the factory turbo silencer.

    Relief cuts may be what solves this debate but at what cost why not just drill a few holes in the silencer you could start small and go bigger for more noise


    The silencer ring has no affect on turbo surge. Surge is when the air leaving the turbo gets backed up because the engine is not consuming all the air coming into it or if the turbo gets over spun , too many rpm

    Re: taking out the factory turbo silencer.

    Are you talking about the silence ring or the VGT assembly? We're talking VGT

    You won't have any issues with the silence ring that you can easily see. You're interrupting the air flow now.

    I've been doing this stuff for a very long time

    Re: taking out the factory turbo silencer.

    Just to jump in on this... As Ray stated I have mine removed. It's been out for almost 2 years now, 50,000+ km and I haven't had a single issue. The turbo is definitely louder, there's doubt about that. I haven't noticed any issues with surging, performance, or any of that. Now that being said, if I was to do it again I wouldn't full remove the ring AND inducer like I did (because that's all I had information on). I would have machined the silencer ring off the inducer to get the best of both worlds. Then you get the noise we all (or most us) want but still have the ventury effect of the inducer. That's something I may still do as I do have the ring still sitting in my shop. It's just something I haven't got around to yet.

    Nope not talking about the VGT. Talking about the ring in the mouth of the compressor. The one that used to be c clipped in and is now held in with 3 pins that have to be drilled out.

    Btw, @Polaraco thanks are in order for being involved with the egr/DPF deletes. Best thing to ever happen!
    @dmuney the drilling of the ring falls in line with the topic of discussion about its removal. If the ring is solely there for NVH, then removing it should have no ill effect on function and would mean the relief cuts wouldn't be necessary in the first place.

    I still haven't heard back from holset, probably due to the holiday.

    That mercury reading would be negligible at best though. And rays truck is the only one I've ever seen pull a negative number for boost on the ultra.
