I drive a 2010 f250 6.4. My work parking lot is off a main road. So sometimes it a drag race leaving the parking lot so you don't get hit. my problem is when i stomp on it start to take off then it act like my truck is confused on what to do. It seems like the turbo trying to make boost and the transmission can't figure what gear it need to be in. It still goes but the rpm never go up. If I let off of it then ease it back in to it dose fine. i have tried it with a cold start and i let the truck warm up . It is the same thing both time. i don't drive the truck fast. on the highway and normal driving it runs fine with no problem. I don't want to put a tuner on it if i don't have to.

 

If you can give us a little information, miles and past history that would help. Where are you located and have you had it checked for codes?
