Default Cold start idle rpm for cammed A4

I've tried a search but mostly finding M6 info.

For you A4 guys with medium to large cams, what rpm do you have it set to on a cold start?

I have my F13 set to 1050 @ -40' and tapering down to 800 @ 176'. It really depends on what the cam likes and how good the tune is.

I am running a G5X3 (236/242) 610 lift... on my Stalled A4... On cold mornings 20deg or less, i have to baby the throttle a little till it finds idle.. once it is warmed up, it stays @ 900rpm... hot starts, fires right up @ 800-900 steady... no surging, hunting idle @ all..

TR224-112. the tuner set the idle at 700. i believe stock is 550 or so. i don't know what it is at cold, which is what you actually asked for.

For "BIG" cammed motors I set the cold idle high, depending on cam size from 1200 to around 1350 + to prevent a MAP code, I am talking cams starting in the
248 + duration range...

I was asking because with my 230/238 cam it is idling at 1350 rpm and sometimes climbs to 1600 rpm while the car is sitting idling.
