[Mega ST]

Oh yes, launched at 5500rpm! Best 60' was a 1.78, average was low 1.80s.

I notice when shifting there is a significant drop in boost and it's slow to recover. I don't lift between shifts, is there something programmed in the stock tune that kills boost and timing during shifts? I know DCT's do it but it's barely noticeable. It's pretty pronounced in the FiST tho.

Yes, once you get a tune with flat foot shifting enabled, that will go away. I remember having that issue on my first Fiesta when it was bone stock, and it was annoying!
