learnning how to tune
To answer the question though, no its not hard to learn, and when you screw up you can just reflash the old good tune you started with.
there are a few very good people out there who explain how do it right, and alot of people who mean well but don't really understand it...so you have to be very careful about what you choose to believe.
theres a couple of good books you can buy as well.
