Yep, try a search on "tune" and you'll have about a thousand threads to read.
For the engine, the tune should be "safe" as long as it is not causing any pinging.
For the tranny, those hard shifts would bother me a little . . . but I'm pretty sure that in a few of those threads somewhere, someone said the firm shifts are actually better for the transmission.
