Missing until under load

[Tsgs69400]

Mabey its just me but it seems as though my truck has a miss coming from the rear of the drivers bank until I get a load and build at least 5-8psi of boost.
I know I have heard others that sound the same but it just dosent seem right. It will get a slight chugging at idle as well. But this does not happen all the time.
Mabey CPS or a UVC harness?

I seem to have a similar problem, slight miss under light throttle, once you hit the throttle a bit harder its fine. Have you had any luck locating the problem? Keep me updated.

maybe the "miss" is an up-pipe leak.mine will chug and blow black smoke until the turbo spools.mine almost feels like its chokin abit until it spools.i believe my problem to be up-pipe leaks,could be your problem as well.

That has been somthing that I have considered but I cannot ever find any leaks. no smoke deposits.

I noticed that lately but only around 1200-1350 rpm..Just give little more throttle and clears up...truck doesn't jolt of feel different but I can hear it if im looking for it.

I was having a similar problem. I checked everything and couldn't figure out the problem. I noticed my dipstick tube was leaking AGAIN. It was low on oil so it wouldn't fire the injectors like it should.

so then being a little low on oil was the cause of the problem? Mines doin the same thing, slight miss and occasional chugging at low rpm or cruising speed.

Ive been told that mine was the uvch. Got to get the money to replace mine. Hopefully that will fix the problem. A friend of mine had the same problem and he changed his uvch and he said it fixed it. Hope this help out.
