Answer 1

Tuning works similarly to how you tune instruments, you’ll be trying to find the balance needed for optimal performance of optimal longevity. When you change your car parts, be it to improve performance or for better ride quality, you need to tune the basics of how the car runs so it’s more compatible with its existing parts.

Here’s a (https://youtu.be/LjZlAzr8MuQ) by Donut Media (man I miss the old Donut Media) explaining it more detail.

Essentially, there are certain points you tune more or less of, and now with computers, you can tune the car more precisely than you can before. Maybe it’s for peak power or maybe a longer power band meaning more power throughout the gear rather than just the best power for one instance.
