have you checked your other thread on this problem? Have you tried the suggestions? What bov are you running? And are you using anything to tune? Like a apexi safc?
no tuning as of now…BOV is turbosmart without any horns so i imagine its one of there smaller ones. i had no idea atmospheric bovs could cause rough idle and rpm fluctiation. also if i were to get my car tuned wuts a good safc for a good price and where do i get it tuned. thanks
I atmospheric blow off vavle “could” cause the rough idle but I hear of people running hks ss and not having a problem. You could recirculate the bov. Or search in the for sale forum for any SAFC. You can tune it yourself or bring it to someone, there should be someone near you. Look around.
