well i picked up my black 6 speed today :-D . what a rush, i love it already, and even better i opened the glove compartment and found the previous had the timing belt service, valve cover gaskets and cam seals all done less than 1500 miles ago. car is at 60k. well anyway, driving it home, a found that if you get on the gas the car really starts to whistle then if you are going slow enough with the windows down in second gear if you let off the gas you can hear air blow off, like a blow off valve sound. so obviously i have a boost leak.... i hope haha

well anyway i see the pressure testers and im wondering if you just put it on the y pipe and put 10psi in it. how does it keep pressure in the system? wont the air just pass through the motor? what keeps the pressure in?
