Tune is not needed for either one but you get max performance when you add a tune with the downpipe.

If you have a JB4, it will hide the code so you can go catless or regular catted (not HJS).

If you have a tune that does not hide the code (JB stage 1, Active 8, Dinan,etc...) HJS are worth it because you will not get a code.
