Hey all, hope this finds you well, I’ve recently installed a short ram intake and an aftermarket muffler and just had some questions regarding if I needed a tune or not. I’ve heard that putting a SR intake won’t do much for me if I don’t tune it, and I’ve heard it will without a tune. I’m generally believing that I would need a tune for it. Second, since the check engine light is on (low responding 02 sensor/p0411), I’ve read that disconnecting the battery for a while then reconnecting, allowing the MAF to recalibrate, thus “tuning” the car and adjusting to the new intake. Can anyone clear this up?
