Barring that, I'd probably head to the dealer and ask them to maybe reflash the computer. Maybe something has gotten haywire and needs to be reprogrammed. That's about all I could think of.
Most likely because these engines are "tuned" to maximum efficiency and to meet ridiculous emissions standards. GM is tweaking every last bit of economy out of these engines, not performance. My '13 is the same way.

Any idea how large that collector cup is on there? Guess the reason I'm asking is I'm wondering how often it will have to be drained.
