I have a 2012 CTS V Coupe with a 6-speed manual. Pure stock it made 458 rwhp. Just a tune netted 491 rwhp. An AIRAID CAI made it put down 516 rwhp. A ported LSA TB made 525 rwhp. And my latest mods (LS9 cam and springs, Kooks headers, and a 9.55 lower pulley) made 635 rwhp. That's about 750 hp + at the flywheel. The car still idles @ 750 rpm, and with stock mufflers it is totally quiet. Sitting next to me at a stop light you would not even look over at this old Grampa. I do not street race, however I enjoy the power from time to time. Last time out on M&H 275-40-17 drag radials it went 11.18 @ 127 (126.90 actually) mph in the heat with the DA of over 1800'. So I'm pretty close to the specs of the Hellcat (hp, and 12.5 lbs of boost) with just the 1.9 blower compared to their 2.4. So the short answer...no the LSA has not seen it's potential limit. I will be installing some Mickey Thompson DR's on my factory wheels for street use just in case.
