How to shut off boost solenoids during engine running.
Trying to get to the bottom of a buzzing sound at idle and 1k rpm..
Under the hood, its sounds like its coming from the front of the engine, maybe solenoid sides.. Is there anyway to shut the solenoids off safely, so i can cancel them out or determine if the solenoids are he culprit? |

Could you just unplug the vacuum line that connects to the stock airbox? I left that unplugged one time, car reved fine, there just wasn't any boost, maybe that might help you out.

It is the solenoids farting in the video as i had the same exact noise. My issues when I had it was the tune creating the wastegates to cause this buzzing and farting noise. Cars seem to be finicky with certain maps and for firmwares, but once I loaded a firmware that I knew didnt make this noise the buzzing stopped. Loaded the maps that had the buzzing noise and as soon I as started the car the buzzing came right back.

JB4 has a valet mode, right? You can put it into valet mode with no boost. That should cut power to the solenoids. If no, then just unplug them.
