Default New fuel plate - How do I adjust it

I have a 1994 Dodge Cummins with a new plate set up for towing. Ran great yesturday at the shop, now today pulling hills I am having problems getting it to wind up. It does eventually but its not running the same. Its like I give it throttle and it has no turbo. Then if I get up to right speed usually 5th gear it will take off again.

I had been running diesel with amsoil cleaner previously. Started running veggie today again. Tech said plungers in pump may be sticking due to veggie? What do you think.

That sounds more like the starwheel needs adjustment to me. On the top of the AFC there is a plug that takes an 8mm or a 5/16" allen wrench to remove. Look in the hole and you will see the starwheel. The starwheel controls pre-boost fueling. Turn the top of the wheel toward the engine about 20 or so clicks. Put the plug back on and try it. If it still feels sluggish then let us know and we can go into it further.

Thank you - just so I am clear you want me to turn the wheel about 20 "clicks" not rotations. The little wheel has spurs on it. Does the wheel click when I move it or do I move about 20 of those spurs?:cool:

Each spur will give one click. When you do it you will feel it.

Default adjustment to plate

Hello Tom - When you say "toward the engine" I am thinking you mean toward the top to the center of the engine - right? I want to make sure I have got this correct.

Do you suppose I should test out the truck after I adjust it with the trailer on and try some hills etc. ... These adjustments can't do any damage as long as I keep the temp down I assume.

You are correct, move the top toward the engine. Another thing you can do is slide the AFC full forward too. Just keep in mind if you go too much you will have quite a bit of smoke when you take off (before you build boost) and your mileage will suffer. Just try to get it to light the turbo quickly but not smoke to much.
The video by ISX should help you understand what I mean.

I just remembered...... Check the boost line that goes into the back of the AFC. If it is leaking it won,t allow the foot of the AFC to pull out of the way.

I checked the boost line it was loose so I added a new hose clamp to it. I adjusted the wheel toward the top of the engine but then I did not have much power on the top end, or thats what it felt like. So I turned it back the other direction about 1/2 the distance. Am I correct in assuming this is a go till it feels right kind of thing?:cool:

Anyway I am going to keep the allen wrench in the truck till I get it the way I like it. If you have some other direction for me on this subject that would be welcome. When I had the shop install the plate I told him it was too hot so he moved the plate itself back toward the cab. I think someone mentioned that I can slide the housing forward toward the radiator and it will give it more fuel is that correct?

I just looked this over again - so I understand how this is working in the basic sense. The engine gets the turbo up to speed, it kicks in and then it uses the full capacity of the fuel plate. Is that right?


I noticed that the truck will sometimes wrap up to 2200 rpm and max out with a temp of about 600F and stay there. Other times it will take right off with no limit on the tac seemingly and the temp skyrockets. Is this how the truck should be running? Or am I missing something?
