4L80E 4-2 downshift??

[AKlowriderZ71]

I need a little help here guys. Recently helped a friend swap his 60E for an 80E, did the segment swap, and adjusted his tune for shift points & firmness, etc. But the transmission does one thing that he does not like.

If it's in 4th gear with the converter locked, and gets on the throttle aggressively or goes WOT, it unlocks the converter, then shifts to 3rd, then a second later shifts into 2nd gear. It doesn't seem to matter what I change, I can't seem to make this thing go straight to 2nd gear from 4th.

Is this just the way it is?

I've been informed that this is normal for the 80E. It can't skip shift from 4th to 2nd after all.
