I just installed my greddy-s bov. Now SOMETIMES my car will hit 3k rpm, and the turbo sounds like it is at its peak, and the rpm's go up waaay slow. The car runs okay, but ive lost a lot of power. Everything is tight, the bov and the hoses to it (recirc'd). Today I was driving it and all the sudden my car just died. Does anyone have any suggestions? Also, does anyone have installation pics. I thought I installed everything right, but something obviously isnt working how it's supposed to. Help please.....it's appreciated.
 
if you have the third nipple connected and ur blow off valve isnt set too soft and if you give it gas and ur car dies it is probably your mas sensor, same thing happened to my car when i was fiddling aroudn with it, just wiggle the wires on the mass airflow sensor around and see how it works. i have the same blowoff valve and i have it on pretty hard (fully tight)

What third nipple? i have the hose from the intake connected, and i have a second hose going to the manifold.

You most likely have your Type-S set too soft. Make sure you have both nipples on the BOV connected correctly, then tighten it up a bit by giving it a turn or so towards 'hard.'

Doesn't the bov come set all the way to hard? I tested it on that, and still got compression surge, now i've loosened it to two different settings, and still getting compression surge

There are two nipples on the back of the type s. Top one connects to the mani, bottom to a boost source.

You want to put the bov on the hardest setting you can without getting surge. Try it w/ 8 threads coming out of the top. You wont get surge and that worked for me.
 
When you have both nipples on the BOV connected properly, compression surge is actually hard to get.. you can set it somewhere in between soft and hard and it should be just fine.
