I was wondering what the pros and cons are to removing the vacuum ball under the stock battery tray. I want to do this because I want to drop my batter down so I can run a K&N off the turbo. I read a few people removed the ball completly and capped the T, will this hurt anything? I am running a stock motor with a Waller hybrid 57 turbo when I get it back from him? Also I was wondering if I should or can do a EGR block off anf what the pros and cons of that are also? Thanks.
