Another vote for 5 Star. I run their 93 performance tune on my Mustang and it's a night and day difference. Shifts are crisp, throttle response is instant. They send you the handheld tuner and the process is pretty straightforward. Definitely a market leader for a reason.

Exactly, @amy_adams10, trampled plants ruin habitats for insects and birds.

Totally. I started doing the same and it's crazy how much difference the small changes make. I'll turn off Bluetooth if I'm not using headphones, drop screen brightness to maybe 60%, and kill background app refresh. My brick still comes along, but half the time I don't even need to dig it out of my bag now. It feels less like a lifeline and more like a backup plan.
