Just picked up a Greddy Type S second hand. Now, this thing has two vaccum ports on it. One is on the black "hat" cover and the other is in the aluminum casting part right under the first. Which one do I plug into the intake manifold boss and do I leave one unplugged or not? Pics to be posted later if we need them. Thanks

When adjusting a BOV, you're looking for a balance between compressor surge at low boost and leaking at high boost. Do a boost leak test at your normal boost level or a little higher, then back off the spring pressure until the BOV leaks. Then tighten it back up a little past the point where it stops leaking and you should be good.
If you're planning on running over 20psi, you'll probably end up with some surge at low pressures, but that won't hurt anything. -------------------- Eric Wort
