Hey everyone, first post.
I originally drove a 2014 FR-S with 100k miles. the fluctuations were pretty bad, close to stalling pretty often. Never really saw it as a problem, when you're driving it doesn't fluctuate and its a common problem. Now I drive a 2019 BRZ. incredibly, the car is built like a 2014. the fluctuations aren't that bad anymore, I can't think of any times I almost idled, but I've only driven 2500 miles. Not only that, but the recalled high pressure fuel pump chirping is also very audible from anywhere in or around the car.

My vin is outside the effected range so dealership won't even look at it, car is out of warranty because of accident with previous owner.
after tune the idle sits around 800. It doesn't dip very much.
