i have the stage 0, and the hks ssqv bov....when you rev in neutral, why doesn't the bov go off? i mean it works well when i'm in all the rest of the gears and i hit boost....i know some other kits, if you rev in neitral, the bov goes off....just wondering if the zpi stage 0 kit was supposed to register any boost in neutral...?

 

does it have some kind of preload adjustment? did it came with any manual ?

 

My HKS goes off when I rev in neutral, but I have the greddy kit. Might be an intercooled thing? And the HKS is none adjustable.

 

its because u arent building boost until the car has a load on the engine , causing the turbine to spool up .

 

Just slowly rev it up, and hold it for a second then rev all the way up and let off, that should open it up
