Thought I saw this topic before, but can't find it. My truck recently feels like it is bogging down between 2-3 and 3-4. Knowing it is not carbureted, feels like only two barrels opening up or like the transmission is slipping. Only mods are cosmetic ones and a AFE dry filter - but the truck really feels like it is staggering.
Truck only has 14k and I will take it to the dealer - but wanted to try and get some input here first. I have not towed anything over 2k with this truck yet - but a little concerned.
Thanks in advance, Mike.

 

Mine kinda bogs in 3rd. 2014 5.0. I believe it is the converter locking up which causes it. From what ive read a tuner can help... but not sure the dealership will.
