ok that makes sencnow that elbow will it conect right out of the AFC inplace of that tee fitting or will it go right infront of the wastegate, also if i crimp that hose going to the wastegate will that help or make it worse?

All you have to do is go back to page 1 of this thread and read - theres lots of info there to get you started...
But, before you do that - do you have a pyrometer and boost guage installed?

Hey, you said that you could throw away the fuel plate and the spring and not hurt the fuel pump? I got a 95 3500,5spd and the plate is all the way forward and the spring is all the way forward and black smokes ok,but not as good as some trucks ive seen. I want to do what u were talking about but im not sure how great of condition the pump is in.the truck has 206 on it and im pretty sure its the stock pump. need more smoke

I dont like the idea of running without a plate. Go with a 100 or a zero (if you do make sure you tweak your governor arm).

If you have the AFC tuned right, the profile of the plate eventually doesn't even matter because the foot of the AFC lever will pass it and push the gov. arm clear of the plate, and it will no longer be reading the face of the plate. Ultimately running without a plate isn't necessarily a bad thing. Yes the AFC can be tuned, not just gutted. The spring tension (which the start wheel adjusts) determines when fueling comes on. You can tune it for more pre/low boost fuel or less. If you are running big injectors and DVS and holders, you will want a stiffer spring, so you don't dump too much fuel down low. And I would recommend running the AFC, however, switching the washers around on the diaphragm can help achieve more Rack travel as well as grinding the foot on the AFC lever. This will allow the fuel rack to travel further and open up the spill ports more. On the older trucks not running a 215 pump, the addition of a 2095 Rack plug is also a good mod.
