2024 Subaru WRX — conservative tune feels great — what should I log?

PistonDaily680Community StarterMay 6, 20262024 Subaru WRX PremiumCalifornia
2024 Subaru WRX Premium, about 27,500 miles. I do not want to judge a tune only by how fast the car feels. Which parameters are worth logging periodically if the goal is catching fuel, knock, boost or temperature problems early? I am in California. If I figure it out I will update the thread. I am trying not to assume the first explanation I see online.

Intermittent stuff lies if you only catch it once. Move a coil or plug on the 2024 Subaru WRX if it's cylinder-specific and see whether the code follows. Don't erase codes until someone who can help has seen them. On “conservative tune feels great — what should,” that was the fork that mattered for me. I'd want a dollar figure or a measured spec, not 'should be fine.' If your situation is the opposite, ignore me. Checking again after work.

I wouldn't throw parts yet. Loaded-suspension checks on the 2024 Subaru WRX catch play that a wheels-hanging inspection misses. That's the branch I'd chase this week. No need to make it theatrical. I've seen both outcomes, which is why I'd test instead of assume. I'll poke at it this weekend.
