This is what I get while trying to open a DSP Tune.

Can someone lead me in the correct direction?

This version of the EFILive Tuning Tool has not been
configured to display this PCM's operating system.
This may occur if...
your PCM has been updated by a GM dealer
to fix a software problem in the PCM.
OR
you are attempting to load an EFILive custom PCM
program without installing the matching *.cal file.
OR
you are attempting to load a non-EFILive custom PCM program.
Please save this calibration's *.tun file
and email a copy of it to: support@efilive.com
so that we can add support for it.
