Thank you, the stock tune was put back by the previous owner since he went with different tuner.

I have a used U7191 that I am going to use on my 05 GTO. I know there are preloaded tunes which came with the Predator. Is there a way to verify if these tunes are as they came from Diablo? Is it possible to download the canned tunes which came with the Predator?

I want to make sure I have done ...
