I tried to update and all my post are removed. Hopefully this one stays and I can update all the info needed.

Something is wrong if you are killing that many widebands. Tail pipe sniffers and condensation if that is what you are doing. I don't know. If I...

I honestly don’t have my tune and log id have to ask my tuner for that. I’m thinking I’ve got a bad computer as I was already suspicious that I...
