Off the showroom floor it was about 24 HP, what do you think it was when you tuned it? What did the S-3 signify?

I suspect they were detuned on purpose for MPG ratings. 🙂

Been a long time but iirc it had 195hp and the S-3 had something to do with the LS3 engine. With under 50k miles it was junk. I traded it in on a Chevy LUV pu. Think about that for a moment!
