I have put a Forge manual boost controller (UNOS)on my Rabbit and with it turned all the way down (and the softest spring) I am hitting 15/16lbs. Its been this way for two weeks now and so far so good. I have yet to hit the 15/16lb and stay into to it for more than a couple secs tho. The motor has the stock bottom end and no head spacer. Anyone out there boosting over 10lbs ? looking for some thoughts.
