I'm not tuned, and have the turboxs sml BOV, but I have it connected to my 6th vacuum block, bypassing the solenoid, and also did the wastegate hack to pull readings off of the intercooler. Working great, boosting at 18lbs, and peak at 20 or so. I love that I can hear the turbo spool up and back down through the BOV when it's not on boost.
