Hey, I was just wondering if it would be a good idea to remove the diaphram and plug the vacum line that goes to the EGR valve. I helped a buddy of mine a few weeks ago put in an new cai in his 01 prelude (AEM V2 cold air intake) and as per instructions we removed the diaphram on his vehicle. I know a lancer is different from a prelude, I was wondering if there woud be any benifit in removing the diaphram.
