Should seriously consider it. Yes it's nearly 450 bucks, but it's cheap insurance against compressor surge and potentially a new motor.
I put an ATS ported compressor housing on my otherwise stock turbo today, and the difference between this morning (stock) and this evening (ported housing) was very, very appearent. My truck is much more responsive, even on the economy setting, and there is no more compressor surge on the street race tune. Another side benefit, the turbo screams now. Before the housing, all I could hear was exhaust when I got in it. Now, it sounds like there is a jet engine under the hood.
It took me a little more than 3 hours to complete the job, which was largely due to the akward position a couple of the compressor housing bolts are in, and having to remove the intake manifold to get the fitment correct, but I am very pleased with the results thus far. I don't have pics of the job because I was racing the sunlight to get the job done, but the ported housing increases the inlet size from 3 inches to 4 inches and adds a machined bleed ring to help smooth out the air flow under load to eliminate the compressor surge which is common amongst late 99 and up 7.3 powerstrokes due to a redesigned compressor wheel. These housings are also advertised to flow 13 percent more air than the stock compressor housing, which I am inclined to believe just with the seat of the pants differences I have noted.
In short, best 450 bucks I've spent for that truck thus far. I won't have to listen to the turbo skipping for a mile and a half uphill with 13k hanging off the back of it anymore!
