It's not turbo tech specifically, it's just airflow characteristics of an engine. Engines are essentially air pumps. The more air you can flow, the more fuel you can add, and the more power you can make. Aftermarket cams are designed for more duration, hence more airflow, ported heads flow better, long-tube headers flow better, etc etc. PSI is a measure of resistance to airflow. You won't have any PSI if an engine is capable of using every gram of air that a turbo or s/c puts out, but the engine will still be using all of the air, so it will still be making power. That is why you can take a 4 cylinder engine and run 25 psi with no problem. The engine doesn't flow that much air relative to the potential output of the turbo. Now take that same turbo and put it on a V8, what do you get? Maybe 10-12 psi? But the V8 will make more power, all other things being equal. PSI does not equal power. Airflow equals power. It's the same concept with a supercharger. My Radix, on my old 5.3, with a 3.00" pulley was making 10-11 psi. That exact same setup on my new 6.0 only makes about 6-7 psi, but I am putting a ton more power to the ground (or I would be, if my 4L80E wasn't eating up most of it).
Brett is talking about how much power that turbo can support. 550 whp can be achieved on a smaller engine running 20 psi or on a larger engine running at 10 psi, but the same turbo can support either setup. (I just made up those PSI numbers, but the concept is what we're after here....)

nitrous uses the same concept as any power adder... results in more air flow. correct me if im wrong, but since nitrous is a gas, it freezes the molecules and compresses them allowing more air to flow.

I think I am going back to a clutch fan setup on my truck - the e-fans suck for towing and are hell on my electrical system. I may go to a different cam too, looking at either the LPE GT2-3 or GT7, they will idle more like stock, which should help out driveability a lot, and they are very popular with the Radix truck crowd. Oh, and my 2.8 pulley is FINALLY shipping today from Magnacharger, more boost FTW!!
Trucker (current setup)
216/224-551/551-116 (with my 1.8 rockers I am at .583 lift)
GT2-3
207/220-571/579-118.5
GT7
208/230-554/546-121
What do you guys think?
