2. also, a quick one for anyone whos using a port. is it able to keep ecl off? i know that once i throw on this exhaust im gonna get a light since i wont have the oxygen sensors in, im just wondering if the port will clear it, and keep it cleared.
3. which leads me to another question, will the ecu start to try and adjust air to fuel ratios if theres no exhaust passing by the oxygen sensors, or will it just say, oh, guess there is an oxygen sensor failure and keep with its normal ratio? and even if its tuned with the port?
thanks all, much appreciated!
