I just converted my factory BoV to FTA on my Flex today.
What does this do for you?
Nothing but making a PFFFFT noise when you lift the throttle under boost.
Is there any downsides to this?
No, the car is speed desnsity so releasing the air from the turbos to atmosphere when the blow off valves open does not negatively impact the tune, factory or modified.
BTW, I couldn't find 1" vacuum "nipples" to block off the factory tubing so I went to Home Depot and searched around, found some 1" rubber chair leg "tips" to use, worked pretty good so far.

Close up of rear portion of intake tubing with blow off valve return hose removed and blocked off. For me easiest way to get to this area and remove tubing was to remove the intake tubing and rotate to access the clamp that held the tubing onto the blow off valve.

EDIT: Found some rubber caps to use instead of rubber chair leg bottoms
