I hear ya Mikey, but Joe P's stuff does have a prety good reputation in the DSM community, and the Pro Z was designed around the 16G. Also, the MBC would not be responsible for this idle / coasting issue I'm having. To me that sounds like it must be either a vacuum leak or an IAC issue.

I will hook up the boost leak tester again this week when I get a chance and see how it sounds..
