Dont know where to start!

I just got my truck back from a little frame work the other day and noticed that it something doesnt seem right. It will still get up and go like it always has but when my rpm's get up it seems like im losing power, plus im blowing smoke like i have aftermarket injectors. On everyday driving i cant really tell but when i really get down on it, it feels like im pulling a huge load. I dont know if its something the frame shop did or even where to start. Any suggestions?

First thing i would check would be your air filter.
might be clogged.

Also, need a little info on the truck.
Mileage
Tuner
exhaust
intake
Auto/manual
what color smoke. I think black but want to ask and how much.
a haze or a fogger system? Lol

I got a little over 250 thousand on it, with a dp tuner that I almost always run in economy, 4'' exhaust, and riff raff intake. My trans is auto and the smoke is black and its definatly fogger

Any codes?

I would still check the air intake for restrictions.

Maybe unhook the tuner and see what it is doing stock. Still have stock sticks?

What is the boost doing?

Do you have any other gauges hooked up? EGT?

So what i have is, it is over fueling.

Gotta figure out if it is because of too much fuel (bad injector or something)
Or not enough air (turbo not building any boost)

Sorry that i don't know the common problems. Just trying to help you diagnose your problem.

I can't tell you to go change "blank" and everything will be good.
i don't know the system well enough.

Yea i have an egt gauge and it reading the same as it always has, I forgot to mention now that I think about it I also just replaced my turbo wheel, maybe that could have something to do with it. Is there anything i can hook up or do to tell if it is my injectors because that was my first thought too. It seams like its sucking for air but everything looks fine also I cant hear my intake breath like I used to.

Sounds like it is probably air.

Take your turbo untake tube off and see if the thing will spin freely.
It should spin easy with absolutely no rubbing!!!

Well its definatley rubbing. Will the rebuild kit fix that? I would think you would have to replace the shaft but the kits that i have looked at dont come with it.
