Hello from Seattle
 

picked up an 05 5.4 screw in Feb. to use for work. lovin it so far. installed my gryphon cs about an hour ago. cleaned the throttle body and maf sensor this morning and drove for awhile first. trying to decide on an exhaust before I order any custom tunes. appreciate all the good info in here.

:howdy: As long as you leave everything from the "y" forward intact, you don't need anything tuned for specifically.
