Most decent custom tunes are pretty close to what you can get from an average dyno tune. Some of the better tune writers are Bama, Brenspeed, VMP and Evolution. Most if not all support the SCT tuners.
The 5.0 can gain about 30-40 RWHP with a good tune as well as improved driveability and, in your case, enhanced shifting.
