Hmmm...I was thinking...in the article explaining the hydro-boost system it said you had to open a little hole on the lid to allow air to come in. I read on t he true slayer's homepage he didnt open the little hole. If I open the hole how would that affect the vaccumm or should I seal it???? By the way, how many MPG more did you get after you installed your system? How does your water catcher work?
