No more air goes thru the ported section.

I'm with you now. So a WW in a ATS housing flows less than the stock late wheel in the same housing, yet reduces the surge too? Or are you saying due to housing size it is a wash. Before you answer, think real hard about factory HP #s and wheel sizes. I might need to think real hard about my math too.

In a word, yes, it's worth it. I don't care what they say above, my boost has gone up with the stock wheel in the ATS. Before, I was getting ~27 (stock wheel in stock housing), now I'm able to hit 30. I've NEVER seen 30 before, and I've had stock turbo with stock wheel, stock turbo with WW, and van turbo with stock wheel. Haven't tride van turbo with WW, or ATS with WW, but from all accounts, the WW reduces boost some (I saw that when I put it on my truck). I lost 1-2psi going to the WW in the stock turbo.

I never said the ATS housing was not worth it, its the best fix for surge on the stock turbo. The WW is a waste of money IMHO... I have run every combo of stock turbo and the best set up was a 1.00 housing, stock wheel and a ATS housing. But that being said there is NO added airflow from the ATS housing.

The reason your boost went up is because the surge was choking the turbo, not because of added airflow. The ATS housing does not flow more air. It is symply a ported housing.

However, I had NO surge with the van turbo & stock housing. The only time I heard the surge "chuffa" is when I hammered the throttle, then let off it. NEVER got surge with the stock housing unless I was letting off the throttle. So, I don't think it was surge "choking" the turbo.
