Guy I know 08 got the di for the cts. But in 08 and 09 there was such a thing as a 3.6 WITHOUT DI. that's a fact. What I was saying about 2010 is that they dropped the 3.6 non DI as an option for the CTS. That's not debatable it's fact. What is debatable here is whether the changes gm made to the 3.6DI for the CTS in 2010 in order to cure timing chain issues was also applied to 3.6DI in the STS. I think you misunderstood me.
