no low end power
Bought truck with no plate. Did the common afc mods and threw a #100 in. Wasn't impressed. I took it back out and now the truck is not getting as much fuel as before. No smoke at all is how I can tell. I thought no plate ment more low end fuel. Star wheel is all the way loose now to see what's the deal. Still nothing.
.... ummm timing ? what all have you done for mods ?

Thought I had my sig. Set up but I guess not. Stage 2 ddp injectors, 16.5*, afc mods the smoke screw is all the way backed out, stiffer spring, 4 inch, 3k, boost elbow, etc all the basic. Ran fine right before I yanked the plate

did you re-attach the hose to the AFC housing? if you remove that or it creates a leak like a crack the AFC foot will restrict fuel as it thinks it is in a low/no boost situation. there should be some sort of an o-ring that acts as a compression fitting to the housing and the tube will go to the intake plenum OR over to the turbo and attach to the line that the wastegate is also connected to.

I bet the governor arm is getting hung under the leading edge of the plate. that will cause this problem too. there is a procedure around here somewhere that will show the proper way to adjust the arm, as it has to be adjusted, for the arm to work properly, when a plate is moved from the factory position.
