Spotted your problem. Your wideband gain is set incorrectly. It goes positive. It should always stay negative. Basically what its trying to do at the moment is add fuel rather than subtract fuel. I have had this happen to me once when i changed the value and forgot to put the minus before it.

Heres the values i use O2 FB Gain INT

Make sure you change the feedback update rate as well to match your sensor. My PLX tells you on the gauge how fast the wideband is responding. Not sure how your gauge works

Mark,
No worries at all on missing my reply. We are all busy.

Thanks a bunch for your input! I really appreciate your help. It's a bit sad that my tuner couldn't figure this out. I will update the settings and upload the map this weekend. It's almost finally done with paint prep and will be getting sprayed this week. I will change all of the settings and let you know if that fixed it, as I'm sure it will. Thank you again for your help!
