Everything said sounds the same to me. The tune is rich, the computer is fixing it for you. It's not ideal but it's working.
If you have a wideband you could see what your WOT fueling is, likely it's on the rich side.
Any gains to be had will not be noticable, we aren't talking like 20-30hp here. Maybe like 1-5hp if that if you took some fuel out on setup like this.
