Default HP Tuners Diagnostic Advise?

Hey guys, new to HP Tuners, but looking to use it to help me iron out some issues before I get any deeper into tuning for power etc.

The car since purchased has exhibited a rough idle, almost that of a small cam... a noticable vibration during a neutral rev of the motor, and an overall lack of smoothness. No huge misses or moments of breaking up, just a consistent poor overall running.

The car has a new fuel pump, new fuel filter, new wires, new plugs. I am looking for advise on what to put in my config to log specifically and any other thoughts on the matter.

Not sure if Im dealing with a possible coil issue, or injector etc. The engine harmonics is whats getting me. Its subtle, but present. (I have had the valvecovers off and all appears normal...

Appreciat the advice on setting up my log. Thanks.
