When I first installed the gen3's I did disconnect the battery. They've been on for quite some time now without throwing a code. The code didn't show up until the last battery disconnect when I replaced my stereo. But after cleaning the maf sensors I've been driving it hard and for long periods of times and so far so good.
I even connected the car to my oscilloscope and everything seems to be running properly now.
