So i just got my swap on the road 5 days ago and it idles great ! Runs smooth but if i am in boost then go to nurtreal it will drop to 500rpm then come back upto 900 then somtimes drop again. Car has nvr shut off thoe. I have basic mods intake full 3inch exhust and fmic and walbro 255 fuel pump no tune. Now i have done research and it sound like it could be my hks bov. I been reading sr's don not like them. Could it be anything els? Also on a hot day when i coast it well rev to 1000 somtimes but when i come to a stop go back down.

An i have done my research just wanna talk to people bout it and see how they feel.!

Thanx guys! I need some advise!

if you are venting to atmosphere and you have a maf - its probably just that.

You just answered your own question, either recirculate, or have the blow off sound at the cost of running funny.
