make shure you clean after the T-body, into the upper intake. some shops like Jiffy lube offer a cleaning system that is a gravity feed through the hose that connects to the PCV valve, and an addative that is put into the tank. Oh it's called full throttle, I have a freind that manages one and did it to my car and I loved it. "he said that you run it very slow and takes about 1/2 hour" Most people are stupid and run it through at a higher idle.

 

Oh at jiffy lube tell them you have a B2B card and you will get 15% off. the service is like $50 bucks
