Default b20 afr in the 9's need help

im sure the afr guauge is right becuz crusing speeds are between 12's-13's but idle is 9's-10's. it starts fine, runs fine and doesn't smell rich. the basemap i have attached is a stock b20 or so i was told can someone help.

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.
