Its Time To Build Some BOOST!
OK bill first I'd change the brpv ref point to the rear of the carb hat were the flow of the charge will follow the contour of the carb hat. And that's were your going to receive your best signal.
Remember that's your enrichment circuit that's normal controlled via vacuum, now it needs the the best signal possible, there's guys running a line straight to the compressor housing of the turbo and not using hat pressure. Also that's how the crutch works but you plumb a outside air source to the brpv cavity. Because there reports of internal pressure in the carb shutting the brpv under higher boost application so that's why thee CRUTCH was introduced.
HSAB is high speed air bleeds, if you are looking down at the top of your carb and if you have adjustable bleedsscrews there the inner bleeds like in the pic I posted a couple days ago.
Vent tube extention are easy to make and all you need is a piece of 5/16 brakeline about three feet long and cut it into two pieces and cut and bend to fit like this
You will need to pull the short vent tubes out and us some epoxy resin to set the new ones into place
