I keep going back and forth on this and need some honest opinions. My 2019 Civic Type R is my only car, I do school runs and grocery trips in it, so reliability matters way more to me than bragging rights at the drag strip. A lot of people online say you should always get a proper custom calibration on a rolling road because generic OTS maps are dangerous, but then other guys say that for a mild stage 1 setup with no hardware changes, a reputable off the shelf map from a big brand is perfectly fine and way cheaper. I don't mind spending extra if it genuinely reduces risk, especially with our summer heat. I've been looking at Dyno Star Workshop because they seem to take a very careful approach from what I've read, but I'm trying to understand if the extra cost of a full custom session actually buys you meaningful safety or if most of the benefit is just chasing that last few percent of power. Has anyone here had an engine failure on a generic tune that they think a dyno calibration would have prevented? Or is this just tuners trying to scare people into spending more? Really confused and I don't want to make an expensive mistake either way.
