Another S/C'd member worried about his AFR

I was pretty sure that lean = more power..? But more dangerous.

I still have yet to buy gauges, so I can't be any help to you guys right now. Although (interestingly, whoopeee) I remember taking some rubber line off something and there being a fair bit of oil/muck inside it. Don't know which line. But perhaps I should get an oil catch-can too.

The guy who did my dyno was saying all cars are different. Some guys make their cars run lean because their car responds with more HP when it is lean. Other guys lose HP when it is ran lean. I guess the Yaris is the case of a car losing HP when running lean at higher RPMs.
