Hi,

I am currently looking at a 2010 or 2011 CTS due to the fact that they have higher HP. When I look at 2009's I see that there is a 1SB and a 1SA where the 1SA has 263 HP and 153 ft-lb of torque and the 1SB has 304 Hp and 173 ft-lb of torque. I was wondering if anyone knows what the difference is and if there is a tuning upgrade to the 1SA to match the 1SB?

Two different engines.
