I'm thinking it sounds like the maf, when I maxed my maf that was the exact feeling. For a quick troubleshoot, I would try switching out a maf with a buddy's truck to see if it helps. I was thinking injectors, but you have already swapped them out. What are your trims and af ratio doing?

it climbs very slow tell around 4500 and then it starts to pull but not very hard. im 100% i didnt cut any wires or smash them or anything.
and as far as limp mode i do not believe it is. wouldnt i get SES light?
o and skeet saw the pics of your truck its looking very good all color matched.

thanks for the comment but lets stay on track, you mention it pulls very slow to 4500 rpms then after 4500 it starts to pull but not very hard, ok but after 4500 will the rpms ramp up quick or gradually climb with mph like any other truck? not neccesarly on the SES light.
sorry i didnt read through all the post ( to many damn pages ) so if i am asking something that has already been discussed just say so.

Dont know the trims, and we have never had afr gauge on the truck. i will contact my tuner and see if he can email me some info.
and yeah there are way to many pages on this post, i need to find the proablem lol
after 4500 it pulls like normal like any other truck, rpms and mph are constant. the trans is not slipping is what im getting at and the tq feels like its operating right.

I just read 10 pages of posts to find out that the last page still doesn't have the answer . I am going to keep a watch and see what you end up finding. I have a 87 Jeep YJ that I put a 6.0 in and it was in limp mode because Advanced Adapters did not send me a transfer case with the VSS in it. That only took 3 months and countless hours to figure out and resolve. I just bought a 07 Max 6.0 4x4 and it is sluggish taking off. No mods on it though - I just thought the 6.0 with 4.10 gears would have some big *****. Good luck to you brother!
