Drivability is always a big issue where emissions are
a concern, because tuning for lowest emissions often
leaves abrupt transitions between power-friendly and
emissions-friendly mixtures.  This can be a particular
problem with large-displacement cylinders when each
cylinder has a throttle immediately adjacent to the
intake port.

I neglected to respond to part of the post you're
answering, so I'll post it here...

There's a great bit online about how to minimize that
tendency through careful throttle body
synchronization.  Let me find it for you...
