I vote rip all the tubing from the Turbo/WG/BCS out completely. Get a GMBCS and a pig tail and use all new hosing. Then say bye bye to the crappy restrictor pill. Then turn your WDC down by at least 35% and go from there.
Just don't use the Acrylic (colored) tubing you will be fine.
I re-did all my hosing with the Autozone brown box stuff over a year ago and no leaks, stretching, or collapsing to date.
Plus, countless other peoples when installing their new BCSs.
