FBO including stage 2 lpfp., n54. Was running E85 bef, have also run some of the other side. Came back to just jb4 map 5 to diagnose issue. It feels like the dvs doubt close, I can hear it venting boost at low and mid rpm as I'm on and off throttle. In the log (which I am an absolute beginner at trying to interpret) it looks like it venting pressure as it builds, then "sealing" things up as boost gets higher. It is really annoying, especially around town or in traffic. I've checked as many pressurized hoses as I can without a smoke test, replaced all vacuum lines and both boost solenoids. Added RB pcv, new valve cover and gasket just in case. Any help would be greatly appreciated. If there is some other logging I need to do, please let me know and I'll do it.
