Well it seems that there are no big gains other than eye candy and a lighter wallet to warrant swapping out the OEM for the Pusher intake. Now if someone would make a post DPF egr upgrade to eliminate the soot that would be worthwhile.

Pusher claims "The Pusher Powerflow Turbo Inlet design results in a 15% increase in airflow over stock ", The Pusher Powerflow Intake Manifold / Turbo Inlet Package addresses the weakest airflow component of the 6.7L Powerstroke engine since its inception: the anemic factory intake manifold.
On the stock intake manifold (shown here) when air passes through the throttle valve it is immediately disrupted by the EGR boss followed by a solid wall – forcing it to be directed in nearly a 360-degree spiral pattern. With the Pusher Powerflow design, we’ve redirected the EGR flow to join the intake stream at an acute angle and have eliminated the “wall” entirely, netting a whopping 66% increase in airflow.
My plans are to ultimately put my truck on a weight loss program, so doing the Pusher is one of the steps needed (for my needs) to achieve this. But I do honestly feel an improvement driving my truck more daily, it is absolutely breathing easier in its current state. Plus the appearance alone and the heat dissipation vs stock is also an improvement and I can reach more components on the engine and valley because of the Pusher. Don't get a one if you feel its not worth it.

That is a good point Jim... I have no plans to go on a weight loss diet in the foreseeable future, however, the farther out I get, the more I start to wonder about what I will do when the emissions stuff starts failing... at that point I may feel differently about keeping it stock. So, that makes me wonder if I were to swap intakes before then, would these parts carry over to a delete? If not, that would be a lot of money that just gets thrown in the corner and replaced for another chunk of money... kind of makes me think more about whether or not I should do some things, and when should I do them...

My intake system will compliment a full delete as will any other intake. A simple block off plate at the egr inlet flange, etc. and the rest will be history. I do not want more hp gains, just a pure diesel with reliability. No more def, dpf, component failure and the ultimate limp mode. I had a '97 7.3 ps for 18 years and it was fantastic all its life, so hopefully this 6.7 will be as good or better.
