Hi all, been a while since i have posted lots going on in the world, but back to the important stuff, i have fitted a catch can and am currently wondering if i fit a manual boost controller (which i am about to do anyway), does this remove the need for a Dawes and needle valve, or is this still required to provide a mechanical fail safe to prevent over boosting? Its a 2003 3lt turbo diesel. Thanks patrolers.
