10k mod and variations

Has anyone else here done the 10k mod or one of its variants to their rigs? I just got done with mine, and for 8 dollars the seat of the pants difference is amazing.

I've never heard of this. Mind telling us what it is? Maybe a website with information on it? Thanks

Basically all you do in the original 10k mod is hook a resistor between the ICP sensor signal and ground wires. This makes the computer think it needs to raise fuel pressure.
The variant I used uses a 5.6k resistor in series in the signal wire to protect the sensor, with a series of 1-1.0k resestor and 3 1N4001 diodes wired from the pcm side of the 5.6k/ICP signal lead to a switch in the dash that is wired to ground. That way I can turn it on and off whenever I want.

There is a lot of information about it on the ford truck enthusiasts forums archives, and here at http://www.forgotton.net/diesel/index.html
On that link they're called the 10k mod and diode clamp mod respectively.

i put a 1k resistor on my truck and i can tell a huge difference. the only thing is it is hard on the tranny cause it idles so ruff. but it is one hell of a cheap power increace. i ran mine to a toggle switch as well

10K mod numbers

The lower the number on the resister, the more power made. I have 2 on my 96. I flip between a 4.7K and a 10K. The 4.7K makes more power at low RPM. but it increases the oil pressure so much that it does not run at high RPM very well because the injectors seem to have trouble opening against that higher pressure. I have also mounted a potentiometer in the line since. I can turn the power down from the maximums of 10K and 4.7K. A 10K pot in line actually returned about 18K with the 10, and about 13K with the 4.7. When the pot is all the way down, it is just like a having no pot installed. I have had the best success with the 10K - smooth idle, but noticable power increase. When I tow, I use the 10K side turned down with the pot to about 14K (less power, but less heat in exhaust). I do no have guages, and I do not want to burn it up, so I run conservative while towing. Hope that helps.
