Hey Goose, I had those same problems early on as well. Before replacing my AOS i went ahead and bought a new MAF and that fixed the weak cold engine issue but it still wasnt 100% when cold. After replacing the AOS, the cold engine power was back to normal and my idle was perfect and didnt hunt around when my AC was turned on.

'FYI I had to replace my new AOS twice, The first one still caused puffs of smoke and the idle steadily got worse, the second AOS actually sounded like it had a 9mm bullet firing out of it and my idle steadily got worse. Of Course the dealer gave me new AOS for free since this is a defect in the AOS they giving me so keep a close watch on my AOS for oil leaks and little bits of exhaust smoke cause you may get a defective unit and you can only replace it free if you report it as defective 30 days from purchase.
