Quick vacuum line question
Ok right now I finishing up my Vortech install and have a quick question. Are both 1/4 inch lines running off the manifold for Vacuum? I'm pretty sure they are, but on all the installs I've seen, they have the boost gauge and the bov line tapped into the same vac line (the fist from the front of the engine). I removed the air pump and put in a block off plate, so now the second 1/4 line is open. I'm wondering if I can run either the boost gauge or the bov line off that second nipple on the mani. Thanks in advance.

One of those originates off the intake manifold. This is the one to use for "vacuum" (boost guage or BOV). The other one goes to that round solenoid thing near the back of the valve cover. This one goes through a bunch of check valves and solenoids and air tanks and would not be a good choice for what you're trying to do.
ps. How did you contend with the CEL when you disabled the air pump?

Well that solenoid is no longer there...it's part of the air pump system. So right now that hose goes to absolutly nothing...that's half the reason I want to use it for something...otherwise I have to plug it.
As for the CEL...AEM EMS...no CEL

The comptech diagram on their website shows the Bypass valve/BOV being teed into the vac line closest the to the drivers seat, ie the one used for the sec inj system, which you are now missing. That is the way my BOV is hooked up, so I dont see why yours couldnt be the only thing attached to that line.
My boost guage runs of the second line (closer to the front of the car), which also goes to the FPR, if I am not mistaken.
However, I have been getting 411 codes with my comptech sc installation, so perhaps I shouldnt be giving u advice.
PS not sure if is different for vorteq

Can the AEM EMS be used to hide all CEL codes? If installed this on my car, would I be able to get it NY state /inspected, without failing due to CEL? Or would it still fail the emissions test if properly warmed up- any ideas Xviper

Not necessarily. The point I was trying to make was that the end that leads to the intake manifold will experience manifold vacuum and boost pressure. The one going to that back "air control valve" will not. If you connect to that one, you'll get nothing.
