Check your intake air temperature sensor to make sure it is within spec.
I have seen cars have a burnt sensor & not throw a code...
The basemap you posted looks a little weird but not enough to cause the car to run that rich.

Didn't tell you to change it. Told you to check it :-)
You could have ohmed it out and saved your self $.
Make sure your cam timing is spot on. TDC
How much vacuum is the car pulling at an idle?
Have you tried leaning the fuel map out?
You may want to post your complete setup specs on here to get more assistance.
Ultimately you may have to take the car to a tuner in person to have it tuned.
