Currently I have the following mods:
HKS RS intake
Walboro fuel pump
MBC
DynoFlash
TBE (on its way)

I'm setup to run 20.5 psi of boost. I'm wondering if its worth it to replace the stock BOV yet or should I spend the money on something else like cams or something. Any suggestions?

 

mr bov would be my next choice!

 

what he said

but if you are not leaking boost then the stock one would be fine

 

I would say at 20.5psi you should change it. Go with the APS. You won't be disappointed. I put mine on a few weeks ago and even at stock boost the car just feels better. Runs like stock and sounds cool too.

 

Which ever one you choose, make sure you recirculate it, not VTA. The easiest and best choice would be the JDM MR unit since it is just a direct replacement of the crappy plasitc one you have right now.
