Vacuum Line Upgrade kit to re-route lines from brake booster to side of supercharger to give your supercharged car the correct boost in order to send sufficient amount of fuel to the engine at wide open throttle. With it connected to the brake booster (which most are) it will not see the correct amount of boost and the car will run lean or short of fuel.

Great news, I was at the shop and they found out why it wans't hitting any boost. there was a twiste tie keep the bypass valve closed. He cut it off and bam my car was hitting 5.5 to 7.5 pounds of boost. he said he never saw anything like it and didn't know why it was like that. Put it on the dyno and it made 395 hp. And they told me the tune was pretty good just a little rich. I ordered a intake from jdm and a smaller saleen pulley, going back in a few weeks to get it dyno tuned once the parts come. The car feels like a whole new car.

LOL! when you install a Saleen S/C you need to tie the bypass valve closed so you can remove the adjuster bolt. You need to remove the adjuster bolt to tighten the manifold bolt behind it. After the install you are supposed to untie the valve. Guess prior owner forgot that step!
