help!!! massive boost leak
I did the pressure test, but could not find the leak. I check all the host and it seem to be fine. I even check TBB and change out the old BPV to new one. for some reason it still a leak some where and my car won't hold boots at full throttle. What else can be done beside take it to a shop ?

If you pressure tested and didn't hear anything, there is no massive boost leak.
Maybe your problem is not a leak... Bad N75? Software problem (limp mode)? Have you checked the codes or logged the car? Those will tell you a lot.

I test it again, but this time not from the y pipe, I blow it in by the bipipe
but still can't locate it. I will have to get a smoke machine. because air don't even hold from the bipipe
