Sounds to me like 12V power problems. Don't know how a reflash could undo itself. You may be losing the Keep Alive Memory for the ECU and your learned fuel tables are being reset to whatever PA uses. If it is a noticeable difference over a short period of time then something is wrong with either the tune or your hardware that controls AF mix.
