Well Mike, I tried the electric fans on my 460 truck a few years ago. It was nice on the coast but I took it on the road to eastern wa. state in 107 degree weather. I found out real quick that I needed way more fan than I had. I know the pricipals of the heat activated fans our trucks have but it could be better. My big trucks have an air clutch fan that is on with out air. The same could be done on our trucks with an electric clutch that would be locked in without power. Even thow our thermo fans aren't locked totally, they do draw some power. Thats funny you should mention the ICP control. I was just at another PSD site and the thread I was reading was about the ICP controllers. This guy said he wouldn't put one of those chaep %#@^ things on his rig. I have one on each of my psd trucks. They are worth every penny. You can stack these on top of any other chip or programmer. Like I was saying about starting over to test fuel mileage. I'm going to go without any electronic mod's first then, the ICP low & high and onto the programmer and see where I went wrong. Keep strok'n it. Talk with you soon. Bill
