Modifying my AFC
 

I am modifying and tuning my AFC, is it okay to run an aftermarket fuel plate or should I run the stock fuel plate with an AFC tuning? I have a #11 plate in it already but still have my stock one on hand. Thanks!

its fine to run aftermarket plates...as long as you keep an eye on things like egts and your tranny can hold up to that and the rest of the performance enhancing stuff

u can do anything u want as long as u got the air to back it up and better airflow out (exhaust) always helps.

Well I got it all back together, it seems that with my #11 plate in the stock position, I'm not getting much more out of it, even WITH the modified AFC. Move the plate forward?

the real question here is why NOT? lol just be careful, don't go breaking nothing and watch your gauges and go for it.

Nice way to look at it:tu: I did read somewhere that not moving the fuel plate makes tuning the afc pointless, I want to know that it is fact before I take it all apart again to move the plate

That is far from fact.

Well I have the afc all modified and seems like no matter what adjustments I make the truck runs the same

what exactly do you mean by modified (be specific with what you did) and that will allow some more knswledgable guys to further assist you. from my experience just moving the stock plate forward should result in a different feeling in the butt dyno

I turned the cup washers into flat, I shaved off just under 1/8" on the foot, and adjusted the smoke screw to where it just touches the diaphragm shaft. The truck ran good but wouldn't smoke and had turbo lag, couldn't even get 20psi until after 2000rpm. I slowly adjusted the smoke screw and after a couple hours I noticed that the truck is still doing the same, no smoke with turbo lag
