I don't know if it was just a coincidence, but I checked for updates the day before I installed my Banks Pedal Monster/iDash system. Once I reconnected the battery, the Uconnect 8.4 system began to update. Access to Performance Pages is much faster now. About 2-3 seconds to load vs 10-15 seconds pre-update. All functions are faster. Tip: Whenever you disconnect the battery, first remove the #37 radio fuse. Reconnect the battery, then reinstall the fuse.
