I've tried both, still happens

My truck does this too actually ever since I put the radix on but, is not a bid deal so I never worried with it. Only on startup it'll jump to say 1500-1700rpm for just a half second or so and settle down to normal idle. I poked around in the tune wondering if any of the idle tables were changed in the maggie tune but, I don't think they were IIRC(been a while since I looked).
I wonder if the IAC jumps at ilde to compensate for the extra load of turning the blower over? I'll have to get the laptop out and check that.

he is running the factory Magnuson Cal. Fuel pressure is 55 KOEO and holds just fine. Truck was driven and Fuel Pressure did not drop below 59 @ WOT. No vac leaks, everything is installed better than any self install I have seen in 6 years. He is local (simi valley) might want to PM him for some weekend work
