What kind of vacuum are you pulling? there is always less under acceleration, so that is where i would look first. since you have a supercharger i am not sure if anything was changed on your vacuum lines. IIRC you will have full IWE disconnect over 15" of vacuum..... should be seeing 20-21" normally.
are you chewing up the IWE's, or the hubs.... or both?

I’ve replaced both of mine once. Next time I am installing these and forgetting about it:

I would agree with mattd17. With your supercharger, you are probably loosing vacuum to the your front IWE's on a consistent basis, which is causing them to try to engage. That will chew them up pretty quick. You might have to take a look at the vacuum routing the ecoboost motors have, and use something like that.

thanks for the info guys! great help and i had no clue i could eliminate them. i think for winter driving i will go with the kit to replace them and in summer i will go back to normal since this truck dont see mud or off road much and i had no issues in summer driving.

In my opinion, they are nothing more than a bandaid for what would seem to be a loss (or lack) of vacuum. If you want to simply lock the IWE's fully you can unplug the vacuum hose from the solenoid. This will leave the hubs engaged to the front diff and your 4WD control will still depend on your 4wd switch.
The fact that you didnt have any problems in the summer leads me to think it could also be a moisture issue, possibly in the solenoid, vacuum lines or IWE's (or all of those parts). If you have moisture inside, it can freeze and cause problems. just something else to check.
Good luck!
