But why would it run well with the Power FC hooked up??? Does the Power FC fix all the problems? I don't think so.

I'm pretty sure the engine has modifications which the stock ecu was and isn't tuned for to handle. And there is a possibility the ECU is fried.

Try checking your exhaust side for leaks if you haven't yet man. Sometimes having a real bad exhaust leak can cause your idle to be rough. And you not making enough boost might connect to that too. Check the whole thing. Maybe your cat is clogged if you still have it too. That could do that too. Check the gaskets on that side. The turbo for exhaust soot, and oils, turbo manifold. You know the drill...thats assuming if you have done it or not man. Best of luck to you. I'm having issues too.

I was actually thinking the same thing, this is what it did...

-pulled the exhaust manifold
-had manifold flange's machined flat
-had turbo elbow flange machined flat
-replaced the main mani gasket (oem 7 layer s15)
-replaced the mani to turbo gasket (oem nissan)
-replaced the turbo to elbow gasket (oem nissan)
-replaced the oil lines (steel braided)
-checked turbo

no leaks

Do you still have the cat attached?

What about your blow off valve? What kind is it?

Cuz i'm kinda going thru the same, and my hunch is on my blow off valve, I have the GReedy RS, I notice you listed you have a GReedy, but what kind? I have noticed that when I close mine just about all the way, it gets better, but mine isn't like yours, mine bounces. I can drive it around, but the idle bounces sometimes, uncontrollably.
