Does anyone have a Boost Graph example for a Leaking BOV?
I've been reading a bit about aftermarket BOVs. The 'general' consensus is that the stock unit does not need to be replaced for most applications, unless:
a) it is faulty/leaking,
b) you specifically want the whoosh sound when changing gears with a VTA/Hybrid
I'm curious to see, does anyone have a boost graph from a leaking BOV, or some before and after graphs of fitment of an aftermarket unit?
Cheers!

last time I checked one specifically i just had 2 boost gauges temporarily hooked up. One at the compressor nipple and one at the manifold - then just drive around and gradually increase the boost - if you find there's a big difference between gauges (other than the expected pressure drop) then something is a miss. Any other wonky ones have shown up on a boost leak/smoke tester.
Another way to test would be blank it off for a few runs and compare boost readings before/after - if there's a discrepency and it's been the only thing changed then very likely it's faulty.
