FSE boost valves..worth it or not?

[Wackyracer]

What do you guys think about FSE boost valves? Are they worth the cash or not? I have a CAI at the mo and a new exhaust is on its way too, but will the FSE impress me for the money or will i just think 'hmmmmm where my fuel go?!'

from what i read its not

untill u decat (with an exhaust ofcourse)

but the car will drink a lot more fuel!
