Hey everybody I've got a 2010 with 3 inch intakes, catless downpipes, midpipe, id1000 injectors with a Cobb ap3. After my car warms up after a few minutes the afrs gradually work their way down to the low 13 high 12 range from 14.7. I replaced the front O2 sensors hoping it was just them but still get the same thing. Reloaded the tune and still it does it. Has anybody else had this issue? I tried searching but couldn't find anything.
