Just learning about AFR's and how they work, and was wondering how they are for a stock map.
Saw some in another post for Dinan, and how they're running pretty rich (11's) above 4.5k, http://www.e90post.com/forums/showthread.php?t=241782
but saw some Procede ones on meth in the 15 to 13 range http://www.e90post.com/forums/showthread.php?t=225510
Learned a bit from this website http://www.bristoldyno.com/tech/airfuel.htm
how lower AFR's are safer, but produce less power so I'm now starting to piece things together as to why some of the different tuning options give different power! Feels cool to learn this new stuff!
