Default firmer shifts 2000 ls?

I see on older models you can adjust the linkage, dont think the ucf20 has this. Is there a way to adjust line pressure to achieve a firmer shift in sport mode? Doesnt feel very sporty and quick at all (the shift timing and firmness).
Just ordered techstream, is this something I can do in the software?

IIRC the UCF20 is fitted with the Aisin A650E transmission the link below may help with shift characteristic upgrades.

There's a post in the GS400 forum to change a setting on the shift line pressure solenoid, firms shifts up decently for a "free" mod (adjustment).
