I just installed a TurboXS RFL bov in my charge pipe between the intercooler and tb, but I'm not getting any blow-off from it, it just seems to surge from the turbo, just like when I didn't have a bov. I have the vacuum line hooked up to the back of the manifold with it's own like(no tees). Also I didn't put any washers in the bov. Could it be because I'm only running 7psi of boost?

btw, I did check the bov with vacuum and the piston does move easily upward with vacuum and harder to move with no vaccuum.

On my TXS type S, I smear a little bit of grease around the cylinder when I do oil changes, helps it open up...it doesn't seem to like to open without it.

what exactly is compressor surge . . . I tried searching and this is the only topic that comes up.

instead of the compressed air going out the bov it is forced back into the turbo causing it to SURGE.

Compressor surge is when the throlle plate closes and it sends a surge (wave) back towards the turbo. If this surge isn't intercepted by a blow off valve it can cause the turbo to spin backwards and put extra strain on the bearings of the turbo. Basically it's not good for the turbo or performance

thanks for the elaboration
