A little update. Got the open loop tune pretty close. I fixed the O2 harness and went closed loop today. Car has never felt this nice. Mid rpm has definitely improved. Feels like a new car. I can't believe I ran almost 3 years with it so rich. I used to see 10-10.2 afr at WOT, got it up to 11 with no knock, 18° timing. Low rpm is still a little rich. Gonna try to clean that up with fuel trim tune. Decel isn't going stupid rich any more. O2 signal is more active. Thanks to GTPpower for pointing out the O2 issue. And thanks to everyone else for helping.
Did an oil change. Was a bit low. Pretty sure oil pan is leaking. Dunno if I will mess with it any time soon though. Just want to drive it now.
Working on a track day soon. Boss is bringing his Cuda, neighbor his Challenger. I've been telling myself for 3 years that I just want one time slip. Think the time has come...
