Intune not letting me change the tune on my 2010 Camaro SS

[hipr29]

I am having issues trying to download the diablo tune to my 2010 Camaro SS. I originally had the 91 octane tune on it, i reverted back to the original tune and tried to install the diablo tune but i keep getting this message on the screen of the intune: TCM has been tuned before by a Diablo Sport product. Please email the TCM_24255637_BackupDiablotune file to support. What is going on here?? Any help would be appreciated.
Thanks

please email or post that file here, it is on the tunes folder on the intune drive.

Thanks

save this to the intune drive and let the tool import it then go to the car and load the update and it will set the tcm back to stock.

So now that i have done all that, can i load the diablo tune or was it already on my car? Just curious to know what my car was set at? Is there a way to tell? Thank you for the help though, i appreciate it!

it was likely stock previosuly.
