There currently is a glitch with the LLY trucks in the current release. Try installing a previous release until it is resolved.

Can you tell me what format to save the tunes in to flash them to a lly

[ScarabEpic22]

All tunes need to be in the *.ctz format to flash with a V2 or AutoCal. That said, if you are an end user of an AutoCal, you cannot modify or resave the tune files your tuner sends you. If you do, you will be unable to flash them because the tuner's V2 serial number will not be embedded in the tunes anymore.
