when I did this on my drive by wire car I was getting a lean code. I think it was only lean during off boost loads, but lean enough to throw a code/CEL. How do your block 032 numbers look? Describe your plumbing like asked below.

Is that hose connected to the intake tube?

It doesn't do anything other then restrict how much air can flow thru it.

I might try to put mine back in when I go back to venting to atmosphere and see if it prevents the lean code as my real one way valve did. I don't think it will work.

the valve on the inlet tube isnt really a valve, its a damper...it allows flow both ways.
