Ecoboost turbocharger "missfires"
#11
The ecoboost must be most of yours first turbo vehicle. My truck has had this "shudder" a couple of times while accelerating and letting off the gas slightly or applying slightly more throttle. I think it's more of a timing issue with gas pedal pressure and rpm in a given gear. I can make my truck do it fairly regularly. It was called turbo bark when I had a diesel so I'm fairly used to it. The ecoboosts bark, to me, is minor compared to my diesel so it's not a bother.

I must admit I have pretty much only had turboed vehicles so maybe this is why I have never noticed this issue in mine. Either that or the fact I live in Florida and it's nice and flat? I do run an AFE intake and maybe that helps my truck too? Maybe I'm lucky but I will go into ford to get the reflash soon.

Shuddering
I have a hill on my way to work where I feel a slight shudder like some of the other oweners have felt. Right at the 55 to 60 mph in 6th gear, giving a little pressure on the gas. I have found if I use the +&- button and lock out 6th gear when this happens the shudder stops
So I also think its the trans trying to deside weather to down shift or not,
going hytec isnt always perficked.

I can get mine to do the puh-chew puh-chew shuddering thing on a particular grade every day of the week when I set the cruise control @ 45mph. It will also do it with manual pedal modulation but not as well. By the way, in West Michigan if the tech can't duplicate it then you don't have a problem.

Has anybody experienced an issue when the vehicle is in a lower gear such as 4-6th and when going up hill and giving it some power that the turbo chargers kick in and out randomly? It feels to me like a missfire/staling but you can hear the tb's kick in and out with kind of like a "puh-chew, puh-chew" sound. It's more aparent in lower gear going up a hill at lower RPM. It's driving me nuts as the truck tends to stall somewhat when this happens. My dealer told me it's "normal" but I would have to disagree. Any others having the same problem?
I have this same problem you have. Mine aslo dumps boost during shift points sometimes. I took mine in and had a reflash and was told everything works right and I still have the puh-chew prob in 6th. I ordered a new turbo solenoid soon as i get it ill post up result. I read a while back someone had this problem and had there solenoid replace and it fixed it. Dunno its worth a try.

Perhaps the shift points do need adjusting or the learning algorithm needs to be rewritten to prevent lugging of the engine and keep it at a minimum RPM for proper engine operation. I would hope that with all the Ph.D. engineers, gear heads, and trouble shooters they can work this out quickly.
I Agree

mine only does it when shifting to 3rd and from 3rd to 4th and only if theres some extraboost. if I drive like a granny it dosn't happen.
