The new.
So yesturday i went ahead and used my boost leak tester that i made years ago. I was able to track down a vacuum leak from the bov nipple. The vacuum line was an extended line using those plastic hose connectors.(they suck ass) Upon trying to fix the leak my friend broke the blitz bov elbow. (its the piece that connects to the bov to a vacuum line) therefore i am using his brand new hotpipe w/ forge bov. We hooked it up and kinda ghetto rigged it.

Here is the diagram of the old setup:


(the connector where the lower tb vacuum port to the bov connected was leaking)

New setup



Ok so with the new setup the car pulls harder than before but now my car has a wrx sound and a weird lag. The sound is only apparent in vacuum but only from 736mmHg to ~250mmHg. However going from 0 to 250mmHg does not. The lag is right after the next gear engaged but if i shift a bit faster with a bit more gas its normal.

Any ideas? I think i might have a slight exhaust leak at the cat. Possibly the crappy ass turboXS manual boost controller?
