Oh totally, dude… that’s how it seems to be here from what I can tell. Reddit certainly had its hyper argumentative people, but a lot of conversations I’ve seen here seem to have a lot more of that attitude.
I have a good buddy who bought an early 90’s Supra that had a larger twin turbo installed on it and a bunch of other after market modifications. He ended up upgrading the fuel injectors and hand-made himself a brand new wiring harness for it and added a flashing utility for the computer. I helped him trailer it up to a dyno a few hours away from us so he could get it tuned. They were able to tune it to a handful of different fuel types… they tunes it for street gas and racing gas I think. They were talking about also tuning for E85, but I don’t think that ever got done. It was a lot of fun watching them actually run it on the dyno… iirc, it was pushing just under 700 hp at the wheels on street gas. It was fucking nuts.
The first step to understanding the material is exactly just remembering what the teacher told them.
