It is hard to really hear over the idle, and no it is not running a hopped up cam, just sounds like it trying to idle on 510cc injectors with an afc neo messing with the MAP voltage and an FMU. You can see puffs of black smoke, and my garage smelled like unburned fuel for a few days after that short run.
Strangely, setting the AFC neo to negative values (-10 to -50) (which I believe should pull fuel) tended to let the engine die, while running it in the plus values (+10) will sustain an idle, just not a good one, and with puffs of black smoke.
I could be misfiring of course too, or something not fuel related.
