By '99 Bianchi wasn't using much Columbus tubing having sort of switch to custom and Dedacciai tubing. I'll have to dig a bit to see when it started but around that time Bianchi was using a hugeish DT with differential profiles and called it their MegaPro design. Top of the line frames came in MegaPro, MegaPro L or MegaPro XL depending on the type of material used in the frame.
Unless you have pics to post for a possible ID I would wander around BikePedia and see what you can find.
Here is a '99 MegaPro XL Titanium frame. Depending on the year and model some DTs tend to look bigger.
