On a standard wrx engine there aren't any power gains from deleting the tgv's and fuel usage is more efficient off boost with them in place. If you start having problems with the valves sticking then that might be the time to consider deletes.
The best way is to source them off a Bug/Blobeye sti manifold and use your wrx manifold with tgv deletes from the sti. It would take a mechanic a few hours to do the work and you wouldn't see any gain.
