I was at the track last night and noticed that after the run i had no vaccume on the vaccume gauge at idle. So i parked the car and hooked a vaccume gauge up and NO VACCUME to hold the by-pass valve open by the s/c head unit. I had followed the small vaccume hose up all the way to the passenger side by the a.c. box and no vaccume there either and i don't see where it goes from there. I don't know where it draws the vaccume from. My question is where does this vaccume come from?

The tube you talking about connect to the intake near the MAP sensor. It provides vacuum for the A/C system. If it's off, your A/C will only blow through the defrost vents. It would cause a vacuum leak too..

I hate vaccume leaks! Be glad you found yours.
