Sorry, I don't have a diagram for you, but there are several things you want to do to turn up his pump. 1) slide the fuel plate forward, and grind it if you want. The fuel plate is located under the AFC housing which is a 1/2 cylinder shaped thing on the top of the pump. This is held down by 4 screws in slotted holes, I believe a couple are "anti tamper" I use a t15 torx head driver, pound it in and then bust them free, and replace them with allen head screws, 6mm 1.5 inch I believe, but don't take that to be 100%.
Under the AFC housing, you will see the fuel plate aka, torque plate or cam plate. It is held in by 2 screws. Mark the stock postion, sliding the plate forward will increase fueling, you can also remove the plate and replace it with a different one for even more fueling, or grind a new custom #0 or #100 plate with your stock one. Re-install the plate. I like to mark it in the stock position at the front edge of the plate so that I can put it back to stock if I want at a later date.

Next when re-installing the AFC housing, slide it forward. this will help with low boost fueling.

I would also recommend a 3k governer spring kit (GSK), or you can shim the springs with a standard 3/8 washer with the center drilled out to 1/2inch. I recommend just buying the GSK, its about $70 and a lot more complete than shimming it with washers, its a better way to do things.

Also you can adjust your star wheel for more low boost fueling. Turning it in towards the front of the truck (spinning it towards the engine) will give you more fuel with low boost. However, you won't have quite as much range with this with the AFC housing slid forward. They accomplish the same thing essentially and it will just make it really smokey at take off.

Add a boost elbow and some gauges into the mix and you should be good to go. Hope this helps and didn't just reiterate things that you already knew. I highly recommend gauges though, at least boost and pyro, this truck will get hot set up like that.

Yeah, if you are looking to adjust the rack, I would pull the pump and have a reputable fuel shop throw it on a flow table and dial it to what you want. Its kind of a pain, but it will be so much better than doing it yourself.
