Nothing that I know of that’s available.

I suggest contacting Hennessey Performance, they might have something already in the works or will at some later date.

Since the old man died I wouldn’t trust Hennessy with my lawnmower. That’s just my opinion. I know of a couple guys that had their vettes SC’d by them, less than 1k miles with engine failure. Both had to go to court. Research will show the stories. That was a decade ish ago.

9 hp gain sure as shit ain’t worth 550.

LOL What do you expect from the stock LGX and Blazer?
If you want more power you'd need a turbo or supercharger (or swap the engine for a V8) - but you'd also need to upgrade the small stock brakes (my only gripe) and tune the suspension to handle the extra power; Overall, the 2019 Blazer is not the best platform to build a performance SUV/SCV.

However, if you have the will and the $$$ - prove me wrong.

The same V6 in the Camaro. Detuned. And that’s all they can offer for that kind of dough? No thanks. You don’t need a turbo or SC to wake this engine up.
