It must have gotten so cheap, and so simple it makes no sense not to have it.

However, I wish GM would quote real world gains instead of the most optimistic of gains. For AFM (or DoD), I would expected economy gains in the city cycle (heavy traffic) moreso than the highway cycle.
OT: In Australia, we're lucky in that we have lean cruise enabled in the factory tune... I get AFRs in the region of 17:1, which renders AFM almost redundant.

I think the '08 CTS will be the first car to get the new DI 3.6L. If Caddy uses DI 3.6L's that leave the current 3.6L so be used by every other division.
