You need the speed or the lunge power?

The plain speed would be useless, as it wont benefit you at all. Lunge power however is general power of your lunge and it will allow you to make more powerful jumps, flying alot farther.

Anyway, i dont remember i ever seen a cvar for plain air speed. Perhaps you need prelagged movement property (see Perkmod or KrX Upgrades or Pills addiction, how they change one's speed).

Cvar you described can be related to controlling directions while flying, but i dont know really.
