+1Don't do it...
Agreed. I have a bov (2008 fxt). No problems at all. Didn t have any performance problems too. With AT, when you want wild revs, you never have to raise your feet from trotle so if there is any ecu (never happened with me) rich mixture, you won t notice it. Have fun dude.Welcome.
Most people on here do not run aftermarket BOVs and will tell you not to install one, but it's your car and your money. Just do your homework and if you end up buying one, get a good quality piece that won't cause a chain reaction of problems with your engine, causing it to break. Dave's BOV FAQ is a good read.
