Street logging has its place but skipping the dyno every single time is asking for trouble. You got lucky that boost leak showed up in the log, but a cracked coupler is something you can spot with a smoke test or just looking under the hood. A dyno gives you a controlled environment where you can compare run to run without traffic, hills, or air temps messing with your data. The street is all over the place with load and heat soak so your numbers move around and you end up chasing ghosts. Do both if you can afford it. Use the street for real world checks and the dyno when you need a clean baseline to tune against.

I've had two same day crowns, one on a lower left molar from 2019. Still holding up fine, bite feels normal. The key is the dentist doing it, not the machine. If they shape it right and check your bite before you leave, it lasts. My first one came from a guy in Clearwater who rushed it and I was back in his chair two weeks later getting it redone. So ask how long they've been doing same day work, that matters more than the price gap.
