[Warhammer 40k] Since the Dark Mechanicus aren't stagnant like the Adeptus Mechanicus are, won't Chaos eventually win through technological superiority?

Any more than they already have, I mean - the Imperium today produces more than enough war, stagnancy, plotting and pleasure/suffering to feed Chaos.

You can't do much research when your laboratory decides what rules of physics it will adhere to at the moment. And it changes very often.

Also, Chaos does not like other following chaos, they are just as likely to be killed by the Imperium as by other Chaos followers(if not even more so). Death tends to stop research really well.
