    Hey guys, I currently have my blow off valve tapped into the solenoid, I’m after a bit of flutter ( not getting any at the moment ), I’ve tried tightening my blow off valve to no avail. Will routing the blow off valve to the symposer delete help get more flutter ? I’m running a gfb dvx+. thanks !
