Automotive RepairDiagnostics & Troubleshooting3MediumVehicle Owner / Hobbyist Mechanic

Car is overboosting despite a boost controller, causing fuel cut, and user is unsure how to correctly connect a dual-port wastegate to the boost controller.

The user lacks knowledge of correct wastegate plumbing for a dual-port setup; existing generic controller instructions may not cover this configuration, and online advice is inconsistent (venting vs. blocking second nipple).
