Dissable or speedup autotune

[royce]

The autotune just set this two values?  This is the same for every hash type and GPU? In other words, for the same hash and GPU, for every type of attack I try, the value will be the same? So, can I safety use it "hardcoded"?

Well, the tuning might be pretty different for different kinds of attacks. So you might want to run it and get the autotuned values for attacks of non-trivial run time.
