To Buy or Not to Buy 2011?

So I have a 2011 F-250 sitting in my driveway. Hard loaded Lariat. Dealer let me borrow it back on Thursday night. I drove it to/from work on Friday and to run errands, etc.

The main reason I was thinking of stepping up from my current '08 to an '11 was the increased fuel economy. I was hoping the fuel savings would offset the payment difference. I kept hearing stories of these amazing numbers, but in reality, I only got 15.5 mpg... And I was pretty light on the truck.

I love the new vehicle smell, but I found a few problems with this 2011 as well:

1. It seems to have a surging problem in stop & go traffic. Several times I stepped on the gas to accelerate (from 5 - 20 mph) to change lanes and I got the normal turbo lag, then it picked up, but then when I took my foot off the gas, it kept accelerating for 1 - 3 seconds. I talked to another dealer and they said the truck needs to be reflashed? Is this a common problem? Almost caused the grill to be in the backseat of the car in front of me.

2. This truck seems a lot more jittery over small bumps. It's smoother over the large ones, like potholes, but it's way more jittery over little imperfections in the road. I have a F350 SRW SB. This is a F250 SB w/ camper package & FX4. Could the FX4 or Camper package be causing this?

There's a lot of things I like about the new truck, just want to make the right decision and hoping to get some feedback from y'all who have 2011's.

I have 5500 miles on my 2011 and have experienced none of the problems that you describe. No obvious turbo lag or any symptoms thereof. I have size 12 shoes and I have noticed when wearing large boots I have accidentally hit the brake pedal and the accelerator pedal at the same time. That's just big footed me and after a few times I have been very careful. I had a 2001 7.3 purchased new and was hesitant to get 2011. Bottom line -- no regrets at all.

I had some of the same issues with my 2011 F250 KR. I took the truck back to dealer around 4500 miles to see if I had all the updates, especially the one for the transmission. I didn't as my Job 1 truck did not receive the update. Since the update, my truck and transmission are smooth as silk.

Overall, I am averaging 16.2 mpg (calculated) for the first 5500 miles. I drive around the Houston area mostly and one tank towing. If I can avoid stop and go in traffic and keep the speed around 68 mph, I believe I can get over 19 mpg. Unfortunately there is no such thing in Houston.

2011 F250 KR, 6.7, SRW, 4x4, FX4, 20", 3.55, ELD

Op I have noticed the same thing revving the engine in park and in drive. Doesn't really bother me though just something to get used to. I made a post about it with not many responses. I do love my truck though. Wouldn't drive anything else.

2011 F250 6.7L

If fuel mileage is your concern, save yourself 15-20 grand and call Mike from KEM Performance.
Get the complete delete kit and the 345 tune, and you will increase power by 80+% while increasing fuel mileage by 50%.

If yo want a new truck, I personally would wait for the 2012.

2008 F-350
KEM 345 tuned.

Decided I don't want to go the tune route. I don't want to void any warranties nor have to put the DPF back on each time I have to go into the dealer.

F-250 2011

If you're going to ask me, I will go for the 2011 F-250 because as what you have said, it has a better fuel economy and of course there will be lot of changes and improvements in the vehicle itself which will make it more convenient and fun to drive.
