Sure tuning is way more then fueling, TBH you can tune via EGT and not even look at AFR if you are experienced enough and have correct probe placement, personally I prefer a WBo2 to relay my accurate fuel readings, EGT FB is very useful in tandam for an accurate balance of fueling and ignition, but hell, look at a rom image from any vehicle, soo many parameters that can effect the ultimate outcome, its a fine balancing act to get a smooth, reliable, well targetted, accurate vehicle.
Thats why I tune my own cars.
Yes I have popped a motor in the name of science lol
