hi, i installed a Greddy RS BOV, with 2 springs, 50% times it'll stall, one spring mod still give me stall sometimes after came off boost and very crappy idle like many other people. got tired of it, switch back to stock (EVO 8), bad idle for about 5 or 6 boost, and everything seems back to normal. Just wondering why does this happen, and anything i can do to fix the idle problem with Greddy rs?? thx

 

Tune it!

 

get a forge rs and call it a day

 

i have that bov in my 8 and now in my 9. Absolutly no problem at all. Maybe you install it wrong. I never had crappy idle or anything you have. Also my 8 had cams too.../272's/
