Preludedude Posted August 11, 2015 Report Share Posted August 11, 2015 (edited) I've been browsing for a new manual boost controller and see some are 3/16" and 1/4" port size? Is a 3/16" sufficient or should I go bigger for the 1/4"? Does it really matter? I have a big 16g by the way...

ucw458 Posted August 11, 2015 Report Share Posted August 11, 2015 3/16" is bigger than the factory vacuum line so you should be fine there. Link to comment Share on other sites More sharing options...
