Correction on "I can no longer open ANY of the 2010-2011 tunes that I downloaded from the link." I kept trying to open tunes (calibration files) and finally found some that would open. I assumed that since the link to the tunes was from EFILive, that all the tunes (calibration files) were already calibrated to be able to be opened up and modified. I will reflash my controller with one that I know can be opened by V7.5. Sorry for the confusion caused by my inexperience.
