I have a aristo 2jzgte with a single turbo. I'm only running a downpipe right now till I get it to a fabricator. Then I'll have them mate it to my exhaust. When I start it up its idles at about 14-14.5 but when it warms up its stays at 16-17. It idles and runs fine, but when i see those afr start to creep up it scares me. What are y'alls afr when its warmed up?
