As stated in Title! Does the 11-12 require a tune when you install the Aluminum DS on an already tuned 5.0? I didn't find a thread that referenced this specifically.

No, but if you change the muffler bearings at the same time, which you should, then yes.
No tune required, but you do need to adjust and clean the johnson rod.

No tune required , but due to less rotational mass and faster acceleration you should go with a stiffer piston return spring
