Strange Idle - after fuel pump swap (E85)

Any codes? Looks like a vacuum leak, or you need a re-tune because ur leaning out on fuel trim 4 a reason.

No codes.

Runs at 14.7. Except for this slight dip. AFR will go from 13-15.5 during the dip or prior to the dip.

Got retuned by seb 2 months ago (issue was happening then as well) because of new fuel pump and ecutek went to v5.

Here's another one today.

This is what usually happens once or twice during the first 5-10 mins of the drive...

I tried embedding this video, but for some reason - it keeps coming back with a play error.
