[QUOTE="Sagittaria, post: 10592829, member: 113330"] I drove it around town today for the first time (I drive highways... live in the middle of nowhere) and it's popped 2195/2197 lean codes a couple times... so vacuum leak it is. I haven't looked into it too hard but I'm thinking that my valve is not air tight (which is critical for the mod to work). I ran a quick line from the lower port of the valve back to the intake (stock) to temporarily fix it but that sort of defeats the purpose of the mod a bit. At boost it'll still close the valve which is fine. But at low load, vacuum is applied at both ends of the err... plunger/piston and I'm not even sure if it'll open the valve or not because of that - especially when there's a spring always asserting a small force to keep the valve closed. It was dark by the time I did this so I'll have to look again tomorrow to see if it opens the valve at all now that I added a line back to the intake. But honestly I'm thinking that my valve is worn and not air tight at all if this has worked for everyone else. [/QUOTE]
