Another sr droping rpms

[Srjustin]

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.

Ok and yes i have stock maff and yes its not recurulated. Thank you anyother opinions?

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