If i am reading this right

You have a new (to you) BOV--which is the HKS one and you have your old BOV.

You have tried the new (to you) HKS BOV and it makes your car run like crap. However, if you use the old one it runs fine. Correct?

I would say the BOV isn't getting a good seal causing your car to run rich and consequentially like shit. At idle you should not notice the non-recirculated BOV.

When you get a good BOV either recirculate it or get your car tuned to run without it recirculated.
