Stock tune doesn't matter, as long as it has passed all (or maybe just certain specific) self tests, and there are no emissions-related error codes, it should be fine.

I doubt many people know specifically about the Hypertech, because not many people use them anymore. There are far superior ways to tune the computer, like pcm4less and madz28 that you mentioned. There is also LT1edit, if you wanna get in and do it yourself.
