Hey nada problem....
If you start the car and hang your head under the hood you should hear a loudish "SSSSSHHHHHHHHHH" which would indicate a leak. Be careful to distinguish what your intake sounds like so you don't confuse the two. A vacuum leak will be more high pitched than your intake so stick your head up to your filter to get a reference. Sometimes it can be hard to find because its like a police siren, you can hardly tell where its comming from! The best way I've found is to put your head behind the intake so you can't hear it as much.
I'm assuming you know what the boost control solenoid is since this will be your second time replacing it. If not let me know and I'll post a picture. If you look at your BCS you'll see a shaft that comes out the bottom and attaches to another shaft that goes into the supercharger. With your engine off the shaft from the BCS will be resting on a small screw head looking thing on the supercharger. When you start your car the vacuum will pull the BCS shaft into the BCS itself and lift it off that screw head looking thing. I'll call the screw head looking thing the stopper nut from now on. When you floor it the BCS pushes the shaft out until it hits the stopper nut, this closes a valve in the supercharger and allows full boost. When you let off the gas it pulls it back up, bypassing the supercharger and taking the boost back away. What we want to make sure of is that the valve in the supercharger is being closed all the way. i.e. the BCS is pushing the shaft all the way out until it hits the stopper nut.
Take a piece of tin foil and with the car running (so the BCS shaft isn't sitting on the stopper nut) affix a piece of foil to the stopper nut allowing a piece of it to stick up. Make sure this piece sticking up is plenty more than thick enough to hold up its own weight. Note how long and in what position this piece sticking up is. Take it for a short drive and floor it only once. Then pull over ASAP and check the foil. If its working properly it should have crushed the foil all the way to the stopper nut. If not you should be able to tell how far it did make it. The idea might take a bit of refining but it should work.
Backing up some....obviously you want to make sure the BCS shaft is resting on the stopper nut before bothing with all this
Lemme know if you have any other q'*
