what is wrong PLEASE HELP!!!
 

I was driving the truck today and noticed that it has no power over 2500rpm and sounds like it was being held back and it was the loudest i ever heard the truck. i just last week retuned the star wheel and i have a feeling its too much air against my stock injectors, but i could deffinately be wrong. someone please help me i dont know if i will keep driving it like this and need the truck!! :argh::argh::argh::argh::argh::argh:

Do you still have the stock gov spring? If so your truck is behaving normally. The pump starts to defuel around 23-2500. Nothing wrong with it, thats just how it was designed. :tu:

ya stock spring in there still and its the first time the truck has really been highway driven since last summer when it was parked by previous owner before i bought it in december it hasnt been registered until this week but thank you for the input ill be buying a 32k spring!!
