Hey folks, doing a PCV and autoTune install. The PCV install was a snap, directions were pretty clear. The AutoTune is not so straight forward and I have two hang-ups, the unit location and the O2 sensors are much wider. For the location, I was thinking here but I was wondering where other people have it positioned. So the O2 sensors are a little larger, I was just going to grind out the little lip on the inside with a dremmel, but I'm wondering if I need to remove the headers completely from the engine. There is going to metal dust and I'm not sure it's a good move. I can get a little bendy magnet in there to gather shavings, but will that be enough, should I be worried about them not blowing out? Obviously taking off the exhaust changes this from an hour project to something much larger that I'm not sure I want to get into. If I take the exhaust off completely do I need new gaskets for the header?
