I'm not sure if this is the right place to post but I figure this would my best shot since everyone uses wide bands here. I don't know much about afr's and I would like to learn more since Im ordering an aem uego to keep track of my afr with nitrous. What should the stock tune afr's be at idle, and WOT? also can you cause damage by running too rich or only by leaning out? While spraying nitrous what would be the most I could peak into lean before causing damage to my engine? And help will be appreciated
