I feel like it takes longer than usual to drop to idle on cold start
with a month of ownership, i feel like the car takes a little bit longer to drop to idle on cold start than other cars (of engines of all shapes and sizes)
am i crazy or is this normal? i typically dont like driving off when it hasnt dropped to idle, but damn i dont have that much time to wait haha

Yes, it takes pretty long to drop to idle. It also does it more often since one of the ECU updates I got. It's to heat up the cats quicker.

Does it help if you park inside the garage and then start it up?

I see, never mind, I thought the garage door would help insulate the sound. Guess i completely ignored physics and the resonance in a confined space. Hence why it sounds so good in tunnels. I call them amg sound chambers.
