If you mean idle issue , do some idle base running airflow corrections in scanner first and see what's happen .
I do have idle issue myself after I set everything where it should be ; I have some kind of hesitation at idle and initial drive between the idle to 1100 rpm, the rest of rpms runs very smooth thought.
