Just finished a head/cam/intake project on my LS-6 2003 Z06. Start and runs really well at this point. No apparent leaks or anything mechanically suspicious. In logging I see that the passenger side is consistantly running about 10% higher LTFT than bank 1. For example if bank 1 is at 1% bank 2 will likely be 11%.
Where do I start to troubleshoot? Don't see or hear a air leak or whistle. O2 sensor seems to be switching voltages properly - just has a lowerverage than bank 1 thus adding fuel. Bank 1 average was right at .450 and bank 2 was closer to .380 or so.

Please give me some ideas or places to test. Thanks!
