Dead spot
06 screw fx4 all stock other than 2" AS... Sometimes when i slow down to turn or for traffic, when i go to accelerate the truck will downshift like it should and the motor will fall on its face for a second or so.. its like an old carb. motor with a dead spot. really irritating .. I thought it was b/c i was running E85 but now i've run a few tanks of gas through it and it still does it sometimes.. Is this a dealer issue , if so i need to get it done my warr. runs out in feb. Or is this part of the drive by wire lag... would a programmer fix it? TIA Billy

yes a tuner definatley helps, but if you dont want to go that route, i heard that there is a trick to solve this.
1) turn key ON (not to start)
2) push throttle pedal to the floor and hold
3) turn key off
That should help.
I tried this and it worked, but i have since installed an Edge Evo and hesitation is a thing of the past.
Hope it helps

There is a TSB to address this concern. I had the same problem and had the dealership do the reflash per the TSB and it helped a great deal. The problem did not completely disappear but it is nearly unnoticeable unless you know what you are looking for.

kd4crs is right, dead spot is dimished, but still lingering there in the background. But it will be better then what you're experiencing now. A reflash might help as well. Theoretically the dealer should do this conjunction with your service visits.
To clarify.....
1) turn key ON (not to start)
2) push throttle pedal to the floor and hold (hold for a few seconds)
3) turn key off
4) process complete
IF that doesnt work, try this
1) push pedal to the floor, hold
2) turn key to ON (not to start)
3) wait 5 seconds
4) turn key off
process complete, start, go driving.
For some reason, since re-reading my post i think the correct procedure is the second one listed, but i cant remeber where i discovered this little trick to confirm.
Anyhow, one of the the methods will work. I hope you find it helpful.
Cheers
