Team's right.
Just looked back at some of my old idle logs.
My Calc load was around 23+-

 

26-30Load Is pretty common range for a few IDLE logs I've seen(ac on). Your g/sec at idle looks good right at 5.5. My personal opinion is porting should not change the airflow at low speed. Since it is being restricted by the butterfly valve. A ported motor IDLES with the same g/sec as an unported motor. The differance is on the top end when the ports become a restriction.

With 5.5 g/sec idle. If you're LTFT of 6 or more goes across idle(0-9g/sec), middle(10-20g/sec) and cruise(20g/sec-open loop) Trim points then scale your Primary injectors.
