 2005 V6 Mustang fuel running to lean? Need answers
a couple weeks ago my check engine light came on and i put the factory tune back in the car and the light went off so I drove it with the stock tune for a couple of days and the light never came back on so i put the 87 octane tune from my predator back in and my s&b intake back on. and the light still has not came back on so my question is this if my engine is running too lean with the tune and the s&b intake system would my check engine light come on or not. because if the car ever starts to run lean and you don't know it your basically screwed. so will my check engine light still come on if the car starts to run lean with the predator tune in it or not? thanks.
