Please Help!!!!

I have bought a 2006 Chevy LBZ 6.6 with EFI live already programmed and ready to go. This truck was bought at a sale and I'm trying to figure out what tunes are on the truck but i'm new to EFI live so i'm unsure about how to do this.........Any help would be greatly appriciated.

EFILive doesn't build or supply tunes, the tunes were built by some tuning shop. If you don't know the shop or there isn't a marking on the switch, there is no way to determine who tuned it.

You cannot read DSP5 tunes out, so if there is a switch in the cab, the only way to change the tunes will be to full flash over the top of what's there now.
