On my 04 cobra, when I freed up the exhaust a little, my boost (PSI) went down but I gained power (vs before the catback and highflow catted xpipe). That being said, I gained power when opening the exhaust up even though my PSI was down. When I added a K&N intake and larger single blade throttlebody, I gained 1 PSI of boost (and made more power as well).

That being said, I think with the TVS you will gain power accross the board with any of the other mods, but it isn't as easy as adding them up.

Talk with LPE .. they will give you good direction.
