my car used to be boosting 15 now it spikes 10 and stays at 10 sometimes 9 but I've changed my bov cause I was told that's what it was and I changed my wastegate no luck. so today I checked it for boost leaks and couldn't find any. and im being told that its my bov again I have the greddy rs bov and im being told to get the hks seqential bov. any ideas?
well I changed my wastegate to another stock one thinking that might of been the problem and it didn't change. and some guy from a shop out here told me that it could be my turbo going out. does anyone know what it could possibly be? maybe a turbo gasket? what should I do?
make sure you zip tie every connection! and also check the brake booster line that hooks up underneeth the intake manifold and try to get a clamp on it or 2 zipties. boost leak test it and make sure your key is set to ON. Also make sure your using this diagram for your setup.

Have you tried resetting the pcm? I had a similar problem to this but mine ended up being the upstream 02 sensor, even though it never tripped a CEL nor did I get a cel code on it.
Nothing major, no turbo going out. Just try taking the battery lose for 5min and reconnect and see whats up. Do some wot when you go for the test drive.

I tried this set up and it didnt work for me with having S2 WGA and Greddy RS BOV. I got alot of flutter, so I put it almost to stock but a small change. Here is a re vamp on the diagram. Try this and see what happens. I was told that you will loose a little psi from putting on the BOV so I just turned in my WGA to get it back up to 17psi. I am no pro but this worked for me.
ha i think you looked at the diagram wrong thats why.
In my diagram i posted the solenoids is as follows
left to right,
left column of ports is = 2
Middle column of ports is = 3
right column of ports is = 1
you still have it hooked up wrong
your rows of ports by what you hooked up your green line needs to be hooked up to the top port and disconnect and cap the black line you have hooked to the Turbo!
