My understanding is the 2011 CTS-V has a detuned LSA engine to deliver its 556 BHP. How can I "undetune" it to get the same horsepower the engine delivers in the Corvette that gets around 630 BHP?

The LSA isn't just a detuned LS9. It has many different parts. A different, smaller, supercharger as well as some different internal engine parts. Different cam.

If you want more power putting the LS9 parts on it isn't a cost effective way to do it at all. You can get more power cheaper and easier through aftermarket pieces. The performance modification section of the forum here has a lot of threads with info on what mods people did to get to what power levels.

I see. Makes sense. Very helpful. I will check the forums.

Thank you!

Start with pulleys and then a tune with new injectors. Cams, forged parts,heads, there are so many ways to part with your money !
