At 3 DP this detachment consumes a full 2,000-point budget. There is no leftover point, no 1-DP splash, and no combination. That is the trade: six stratagems and four enhancements instead of the three and two a 1-DP detachment gives you, in exchange for having no second detachment at all.
This is worth stating plainly because published advice has said otherwise. If you have read that Virulent Vectorium usually forms the core of a list with a cheap 1-DP specialist bolted on, check the arithmetic: 3 + 1 is 4, and your budget at 2,000 points is 3.
At 1,000 points the budget is about 2 DP, so Virulent Vectorium is not available at all. At that size you are choosing between a 2-DP detachment on its own or two 1-DP detachments together.
What you get for the price is depth. Six stratagems, four of them 1CP and two of them 2CP, cover the Command phase, both Shooting phases, the Fight phase and the moment a vehicle dies. Four enhancements with no character restriction let you kit whatever characters your collection actually contains. A 2-DP core plus a 1-DP support gives you nine stratagems, but split across two narrower lists that each want a different kind of unit.
