Default Smart warm-up injection?

Hi there...

Recently noticed my 2500 Hemi has kinda weird behavior at cold starts. It revs up to 1000 and back to 700 in 2 seconds cycles approx. This lasts some 30 to 45 seconds, then it stabilizes at 600 or so... it seems like a warm-up time performed by the ECU... could it be? Has anyone notice something similar?

I have the same cold engine probs. I didnt know if it was a result of the superchip or if we messed something up or just a common problem. I bought the tri tune micro max 3714 for my truck a while ago and didnt know if it was a direct result of that or not. But we have since put the cpu back to default settings and it still does it, so i too, will be looking for responses on this one.
