Every vehicle is different. If you want to add lean burn you have to remap the fuel trim table.
If you just trick it into lean burn then it runs lean all the time when it shouldn't and you burn valves and at that time it's pretty much get another engine.
I only know because I have been there and done that.
Do not trick your engine into running lean, do it right or pay the price.
