You may have the correct map, but your ECU Co numbers are leaner than what the map was made against. Factory settings are notoriously lean. You can do one of two things. Either richen the mix with the PC-III or bump up the ECU Co values 2-3 points for each cylinder. Here's a link for ECU adjustment. It's really very easy.
