Just got back into town and yes the surge is evident on level 3. I switched back to level 1 after 3 tanks of 91 octane on level 3, about 90 gallons so I know there was no octane dilution. Just saw another post regarding the surge but I do not have a FFV truck. I did get a reflash before installing the Gryphon from the dealer for mystery shifting and that did solve the problem completly (mystery shifting not the surge). Yes it does feel kind of like the TC is confused under very light load.
