2011 Coyote Mustang - Headers, etc

Hi,

Please help, investigating what it takes to convert our project car track only, and going catless. Looking through the tune repository and posts here to find out what needs to be adjusted for a Coyote with BBK headers and no cats.

I get the transport delay so no help needed there.

For catless tho, I'm confused. Looking through "catless" tunes in the repository, I am not seeing any real changes from stock looking at my existing calibration. When I run a compare not noticing any of the MIL's disabled, or catalyst test and MIL disabled like I thought I might see in these "catless" tunes in the repository?

Can anybody point me to a list of which settings to disable when going catless? Or is it possible this car already had those parameters adjusted for catless and later they put the cats back before we bought it?

Here's the current calibration...

Edit, here's my attempt at what I think I should change... am I close, anything wrong? missing?

You'll need to disable all MIL lights dealing with catalyst efficiency and b1s2 b2s2 ONLY OFF ROAD USE
