Will a diablo tune void my engine warranty, and if so, will a canned tune reduce my engine life?

Will the Diablo tune yield better MPG's than the 91 Octane tune?

I tested them both, exactly the same and they're just as fast, diablo feels faster though, but it isn't with premium fuel according to my gps, maybe with race fuel...II feel safer running the 91 tune since they are a copy of each ...
