don't have the stft/ltft, maybe when add the obd gauge but you're right my afr is pretty boring. usually starts up just off 14.4 then bounces around a little then settles there unless on a true coast then will 19.9, that said a very important gauge to immediately show an engine issue. & storm like 4dr said had my egt on my factory dp's& my guy had no trouble putting it into the ppe catted dp's. now that's a gauge with a lot of action.
