The high side is designed to only work when you're on boost, not at low speeds or decel, that's where the low side occ come in to play. You changing from closed loop to vta is causing the blue smoke. Maybe you have an underlying issue that the bms high side occ was masking? I don't vta so I can't say much about that. Maybe your hoses are switched? Got a pic of the install?
