doesnt seem to want to get up

I'm new to this truck and all but from a dead stop she seems like it doesn't want to accelerate hardly at all. Its almost better to "roll" on the throttle then just stomp on it. I understand the turbo has to spool up, but for the first 2000 rpm its like there is nothing. Then after about 2k we have full boost and we are zipping right along. It just seems strange, and I wonder if this is normal.

Yeah, I won;t move my truck until it has idled about 5-10 minutes if it is cold. If I try to go with it cold, it bogs and doesn;t want to move hardly at all. (I do have a tune and it dumps fuel faster than it can burn while cold)

Absolutly.. I could be in it for an hour and it still acts this way. I would compair it to traction control being on..(which I don't think it has) its almost like the truck has to think about it for a second, while it slowly accelerates. And once it figures everything out it brings on the boost, and zoom.

What are you comparing it to? Most any large turbodiesel is going to seem a bit sluggish off the line compared to a gas engine. Of course, put a 15k pound trailer behind it, and see which one is slow getting moving.

Mine is a bit slow off the line, no matter how much you hit the pedal. Once boost builds up, here we go...

Sounds kinda like the the vgt system isn't working properly, if u got less then 100k miles on it I would take it to the dealer and complain, take it to a dealer with a GOOD diesel tech, and don't go by how good they say they are, if it's got more then 100k I would take the weekend to take the turbo off and clean it and clean ur egr cooler and pull the egr valve out and clean or replace it. Cleaning it usually only worked for about 15-20k miles before I had to do it again

I'm in the process of doing an egr delete, I'm waiting on a icp and gaskets for the oil cooler because I got a couple oil leaks and I think those are the cause and since I had my intake off and the turbo was off I cleaned my turbo and intake manifold, B12 works wonders on soot, but the turbo comes apart at the big v clamp on it and mine came apart with some good tapping and a little prying, but when u take it apart make sure u mark the housing where the vgt cam is at, search cleaning turbo on here and there is a very good thread showing how, and a drimel will help with the rust and the scaling, and I used a good amount of anti seeze on everything from the inner part of the unison ring to the pegs for the vgt fins, check for shaft play and check the fins for damage replace all o-rings anywhere u find one.
