Subaru Turbo adjustable waste gate Pil

Don’t follow this or try at your own risk and i’m an idiot please note.
I’ve an Impreza UK300, was told by a friend Rich of Fflat Four Wrexham a subaru specialist, did i know about a pil located in the pipe from the inlet to the t section that restricts the actuator and increases boost by subaru. Mine didn’t have one, i’ve had the car 13yrs now and 127k miles same engine and when bought had only 43,000. It’s been strong and reliable unit and car.
I added a 1.2mm pil from ICP Car Parts from subaru and made a noticeable difference. I went to make a custom 1.1mm and boost came on far lower in the rpm then without a map goes off and after having a integrale BBR conversion it used a brass valve in the same place hence this video.
I’ve no vacuum gauges etc so used an amp meter, small dc vacuum pump and it shows me a datum to work off and can set the adjustable valve to suit without guessing.
Thanks for watching and i’ll update on the result.
