So I need to run a tube all the way to my garage? Are you sure there's not an easier way?

The Wastegate is not recirculating anything. What you guys are talking about is venting the exhaust gasses from the Wastegate into the exhaust piping.

The reason intake By-Pass can be called recirculating is because it's recirculating the metered air back into the intake system..

Recirc is only done on the intake side of the turbo.

So the exhaust vents itself back into the exhaust?
I think you are talking about DEI

So it is really a bypass then, cause you bypass the turbo by going from mani through WG back into the exhaust. Is bypass really not the same thing as recirc.?

Yes, a by-pass just not recirulating back in to the engine.

I had a DTA EWG on my Forester turbo. Annoying as hell. If I didn't sell the car I would have replumbed it. You do lose some whp replumbing it. This has been shown time and time again over at NASIOC.

Awesome to 20 YOs = annoying to 40 YOs.
