the " 10K mod" is putting a 10k Ohm resistor across some ICP sensor wires to fool the PCM into driving up fuel injection pressure which generates more power. Good idea to have an EGT gauge if you want to do this mod. Click HERE for a link to one of our sponsors who sells a kit and to get some gauges
....HIGHLY recommended. Don't add power without them!

Here is a link to a common mods thread. Just be careful, modding is like peanuts, can't have just one.

i have read that one. i was really looking for better info on the mod for the in tank pump, something about air??? and there is one more that has a 2nd pump for fuel under the hood???

 

This is a little fuel system explanation I posted in another thread:

I'm not sure how familiar you are with the 7.3 fuel system, but let's just say it's a poor design. Let's start at the tank. The fuel pickup/mixing chamber inside the tank mixes hot aerated fuel with fuel going into the pickup and if you are below 1/4 or so, air gets in through a flapper valve on the mixing chamber. The quick connects before the fuel pump also let in air. The fuel travels to the heads, one side to the front, other side to the rear. The problem is, the fuel rails dead end. There is nowhere for the air to go but through the injectors and this will ruin them over time. Not only that the fuel becomes very hot sitting in the rails. To correct that, we remove quick connects, modify the pickup and run the fuel line to the back of the heads on both sides and put return lines on the front. This eliminates most of the air and allows any air left to flow through return rather than through the injectors. The factory pressure regulator is capped off and the returns are sent to the external regulator and back to the tank. The cost can vary depending on what kind of fuel lines and fitting you use. I used braided stainless and anodized fittings, total for the regulated return was in the $400 range. You can do basically the same thing without regulator and brass fitting for under $100. It can be a pretty involved job, but if you study the fuel system and do some reading you will be able to do it. Some parts of the job are a PITA though. Well worth the money and time IMHO. A lot of us are also adding a high volume, low pressure pump between the tank and stock fuel pump.

I'm sure I have others, but have to get going. Hope this helps.

You'll need a good shop with some tools to be able to put your fuel pump in the tank.
I highly recommend the procedure BTW. It made all the difference in the world. In fact, I now feel that I should have done that first before all the other mods that have been done to reduce fuel cackle. That probably would have been enough without having to put in air bleeds, external fuel pressure regulators, etc. There is now ZERO chance of any air getting into my fuel supply.
