I run no dump valve or efi pipe and have a td actuator and the solenoid works mate. It takes me years to upload pics on this too have you facebook? I realised I wrote a pile of pish the first time explaining ithis ill try again lol cut the bit of hose between your hks port and turbo nipple in the middle, put the tee piece here, and run a line to the bottom port of the boost solenoid, leave the top port open. Then just a case of adjusting actuator so when on hi you dont hit fuel cut
