So i have a 5sfte and im using a NEO to tune with 460cc injectors. My problem is that sometimes the car runs fine and the wideband reads in the 11's. but randomly the car with run way too high of an a/f ratio. even at idle sometimes i need to take fuel out to get an 11 and sometimes i have to dump fuel in. what could be causing this random a/f issue. my IAT sensor hasnt yet been put into the piping but i doubt it can make that huge a difference, other than that i dont know.
