I am pretty sure my '99 F450 and '00 F550 do the same thing I always just thought it was some kind of load surge on the engine like A/C cycling on and off or somthing like that.

I softened the GDU3 MFD in the low ranges, smoothed the rest of the map up a bit, and I still experience a pretty hash jerk when I let off the throttle and the R's are up around 2k and the TC is locked. Fheww......
I tried softening up the MFD map even more and I started to experience a dead pedal, which is not much fun to drive with. I know I am missing something here.

Well I was feeling really great about my truck tonight, I got alot of my issues solved. So I decided to try a previous race tune ...............and I thought I heard a ping on one of the programs. Not being sure what the noise was I dug around to make sure there was not anything loose inside the cab.........bingo, found a chew can rolling around in my door pocket.
So I proceeded to try the next program on the list and I heard it again, but this time a bit louder and a little more frequent......and that program had even less timing..........uhh ohh.  Cab is getting completely cleaned out tomorrow and I will try it again.

Okay.......few more questions.......lol.
Any idea what the purpose of the Fuel Density Multiplier is? Which function controls the "high idle" speed and temperature? I have played with the High Cam Idle adder and it seems just to be an adder to the base idle. The Cold Idle control appears to be what I am looking for, but the RPM values seem way off.
