seems the std n75 isn't very reliable and there are some problems with fitting atmospheric valves.
does anyone run an after market dual port bov?
if so- any probs with it?

Not heard of std N75's not being reliable myself yet.
Some probs with peeps trying non std (for their car) N75's getting soft limp mode and overboost tho.
BOV's (atmo DV's) generally upset the ecu as I'm sure you've heard. Its an airleak in the ecu's eyes, as metere (from MAF) air is dumped externally, where its adding fuel as if its still there. Running rich, smelly kat, and stalling at junctions are a_typical symptums. Some dual atmo DV's have appeared on a few std cars, but then not worked when chipped. (much more boost to dump and much larger differential in lost air)
