I have noticed that around 1200 rpm's that the truck misses, jerks, quite noticably. I have adjusted the timing advance (using 93 oct.) up and nothing, it only happens in the high performance setting. I am at a loss with this one, I have made sure the Edge is current on all updates, and checked all the basics (I think), any suggestions?

Thanks...

 

It's probably the K&N you have on. I had one on mine and it did the same thing so I put the stocker back on. I did the DUW mode to the stocker and it felt the same as using the K&N with level three without the jerkiness. I have to run level 2 now with 93 octane and +3 timing so I don't get the tranny shudder in O/D.

 

what does DUW stand for?

 

I can't remember what it stands for but you can do a search and should find the posts about it. Basically you take the small end off the stock intake and replace it with a piece of PVC pipe that fits tightly on the end thus making the air inlet bigger at the fenderwell.
