I just notice that under full boost and when I quickly let off the throttle it sounds like a small flutter. Just wondering if that was compressor surge or if that was normal bypass operation. I did not ever hear that with the stock airbox on. This is with 10 psi on a 57 trim if that makes any difference.

does it sound like the three stooges or more like a waWHOOSH! i have the same intake/recirc and im not noticing any problems, if it is i would check the vacum, as if thats kinked that might cause a problem

i have a CT26 on 8 PSI with the same intake and i think its just the stock bypass blowing off out of the filter.

mine is doing the exact same thing now justin. with the stock turbo i never had a single problem. I'm not even boosting right now until I get a different bov, cause im getting surge with the bosch. No problems at all in the past, and dont understand where the problem is now.. pretty weird.

Where are you getting your vacuum source at? Up until yesterday i just figured any vacuum line on the car would be enough but it isnt. I used the vac nipple on the front of the intake manifold for my ssqv. Before i just teed into a line from the back of the manifold and it wasnt enough now my bov opens up at 3 psi.

Well I think I am going to go buy one of those vacuum nipples with the 90 degree angle. I think the vaccum hose might be getting pinched. Btw I am using the stock vacuum source.
