Umm, no, I didn't hook anything back up and decided to leave the intake box and upper i/c piping completely off.

I ranted and bashed the shops for their ignorance when I saw the backwards recirc. valve, but now I see that in all probability they just didn't know any better and were putting it back on the way it came! Which is why I do all my own work around here...
I think some of the assembly line workers in Japan-land were a little .

I'm actually surprised D.B. didn't see it when tapping my boost line to their dyno computer. Wasn't exactly looking for/ at it, though.

That doesnt even sound like its working, and the noise you hear is the TURBO stalling, not the BOV.....

It works about 60% properly that way, I just did it for shytz and grins just to see how well it holds.

It builds boost faster, harder, and holds stronger than any other setup I've tried - it's just so dam noisy and, well.... a little strange

I had to install my Forge DV backwards because the vac line was too short. Works fine though. Although now I'm not sure if I'm just getting flutter on occasion, or compressor surge. It only happens at high speeds in 5th when I'm "lazily" excelerating like someone else said. Modulating the throttle if you will.

When my engine is semi-cold.....and i give it boost to about 15psi....then go back to "easy driving" i have fluttering sound..... is it b/c the engine is not up to proper temps yet?..... and sometimes it sounds like the spring is stuck and then i give it boost and its fine? confusing sometimes.
