Everything i've got was taken into account when i ordered the Maggie. the gears and tire size was an option though on the programmer

I've tried both, still happens

Simi Valley off the 118 at Yosemite. I rolled up in the black lifted truck when i picked up the Radix from you a few months ago. Me and you were talking about some Dynatech Headers if you could find that y-pipe. I'll give you a shout tomorrow.

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.

i will check his truck out, but this is pretty normal if its doing what i think it does. The DBW trucks do this even stock, it is just more pronounced with the blower.

There is a underspeed and overspeed spark table that you can use to help fix this problem in the spark table section. Just pull more timing out.

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
