Cobb's website is abundant with proper off the shelf maps that you can use to calibrate the settings in your car. However since your car is modified and running that rich under peak boost, I wouldn't be surprised if their was a pre existing open source tune from the previous owner under conditions catered to their location (octane levels, elevation, etc).

I would contact a local tuner with the proper tools to determine whether or not your car does indeed have a pre-existing tune before acquiring an accessport.

If not then there are instructions via Cobb's website where you can scale back your injectors, load a map with your same injector size etc. I do know that these cars can run rich from the factory as well.

All the best,
