Gonna say yes and no as to do you absolutely need it tuned. Regardless, you're going to see gains, it's just a tune is like shining your shoes. It optimizes basic engine principals like air fuel ratio, engine timing and lets you set your own parameters for things like speed limiter, rev limit, etc.

Problem is the ecu has been a hard nut to crack and the true tuning capabilities is still a black hole. The honest answer is no one really knows.
