A performance tune solution (like E-Flash) will update your DME to latest specs as well as load a performance file. We recently started a FAQ that should answer most questions in this thread here:

ESS E-Flash ECU Performance Software Cable Overview

For locals, we update through autologic. Feel free to contact me if you should have any questions.

This scenario is likely the only time you will see a performance increase when updating software versions. It's simply part of planned maintenance.
