I'm sure this gets covered a lot but I couldn't find solid information through searching. I have a 2005 corvette Ls2 T56 with a vararam cold air intake and MagnaFlow cat back and I am running 91 octane. I plugged in my trinity which has been updated to the 1r13o gm file. But after opening the performance box on the tuner I only show options for modify stock tune and the factory back up. When I clicked modify it backed up the factory tune but won't allow me to do anything else and gave me the error to call for support. I have attached the factory backup that I exported off of the device. Are there any premade tunes for my car?

you have a very old cal on that car, Id strongly advise having the car updated at a dealer then try the tuner again

So you want me to go to the dealer and have the pcm reflashed?

yes.. dealer needs to update the ECM to latest GM programming..
