lean afr at idle, yes i searched.
mods:gt3076
tial external wastegate
tial Bov
big fmic.
tuned on for 24 lbs
stock injectors stock fuel pump
problem started abouta week ago i got a Cel for a cam sensor. finally got a new one today installed it, drove it , cel went away (didnt clear codes scanner is at work). but my afrs at idle are pegged lean. my wideband(aem) is just lines. if i blip throttle it kinda goes back to normal but when i start it and at lights it sits lean, also the idle tries to die before car is warmed up. when it surges it goes all the eat lean then rpms drop very low sometimes cutting var.. car feels like it has a bad boost leak to but I have gone over everything and cant find an issue. car is very slow compared to usual. im just stumped at this point. my voltage at idle is 14.55 until idle drops and almost dies then it takes a second to pop back up to 14. so i dont suspect its an alternator. i thought maybe my pump but during boost and cruising my afrs are fine, is it safe ro drive like this if i dont beat on it? need mt car this weekend but scared with these conditions.

What does your LTFT low look like? It might be a good idea to pull the battery and clear the learned values then let the car go through a few learning cycles idling at operating temperature.
