The car is basically stock other than the tune and header. The vast majority of my driving is 30 minute commute to and from work. This sample was taken after about a 20 minute drive.
One of the o2 sensors in the header keeps coming loose and vibrates. It does not come off because it would have to twist the wires to get off. It only turns about 1/2 a turn but it is enough that I can hear it vibrating at certain rpm.
I am guessing that could be throwing the reading off and causing the system to run richer.
