Call me stupid, but you are saying my current IC flows too much compared to a stock 7.3 IC? That might be possible. I don't love the CX, but it was available and affordable at the time. I may just rebuild my turbo and go with an E99 setup for easy removal. I don't think I want or need to get into all the internals. of my motor. I gotta think on it. It runs so well now that I don't want to mess with it. I also may consider a water/meth kit and go that route. From the reading I have been doing, it cools EGTs AND provides a little more power/boost. But then again, that may present the same issues with too much boost? Aye yie yie, I just wanted a better turbo setup 
I updated my signature so you guys can see or be reminded of what I have done so far.

You could run a 366 with stock head bolts if and I say if.. (let the peanut gallery erupt) you are careful with the go pedal.
Heck the hillbillie has had stage 2s and 366...just don't let it see 40 hanging its tounge hang out racing any camaros lol

A more efficient IC will have less backpressure, flow more air and have a lower boost measurement due to less pressure building up upstream of the IC.
But, downstream of the IC, where it counts, more air flows through the more efficient IC and so the pressure builds up higher between the IC and the cylinder heads. Due to the higher air flow, pressure measured downstream of the more efficient IC will be higher than the pressure downstream of the more restrictive IC.
Hope that makes sense.

I think what he's saying is that since you're measuring boost upstream of the IC, a more efficient IC will flow more air, have less backpressure and your boost gauge will read lower. A more restrictive IC will have more backpressure, flow less air and result in a higher boost gauge reading due to the pressure building up in the piping between the turbo and the IC.

Soooooooo, I have a Diesel Innovations very, very expensive IC and I'm bitching about low boost. Maybe I should put another boost gauge on the downstream side of the IC to compare? I just can't image it being higher?

Just remember boost is air movement
Under restricted flow path.
in my head the turbo flows "x" and the engine processes what can be crammed into the cylinder. If the engine were the restriction I would think head intake port pressure would go up followed by the rest of the system. At the Rate the 366 compresses I doubt any of that could happen.
Glenn, you had an aluminum 7tree ic before. That core is very much smaller than the DI inter cooler. I have a suspicion if you had swapped the inter cooler by its self you would see less boost pressure. If we checked cylinder effictive pressure I would bet it went up.
Wow, my head is spinning.

No sorries here. You're family, soooooo.....anyways, I don't think I would lay on the go pedal like that. Maybe I can do the upgrade, keep it under control, and then do the studs/spring/rods on the next phase. I gots lots to think about. I am used to being careful with it now just due to EGTs and having to keep those at bay. In stock or 50 setting, EGTs are not a problem, but anything above 50 and I have to watch my go pedal quite a bit.

I will say Glenn, and prolly get flamed, but my Dodge never had these sorts of issues. It pulled fantastic and I couldn't get the EGTs above 1200 if I tired. It was a $450 payment every month though. Trade offs I guess.

Yes I suppose some do. I prefer not to hang out with those people from broke back mountain lol
