About halfway thru this thread, Morgan answered my question about changing the 7.3 stroke. http://powerstrokearmy.com/forums/archive/index.php/t-55394.html
I picked up 90 horse with an air to water running a small pump, garden hose for lines, and water right from the well. They definitely make a difference.
I have a 3 way switch on my truck for pulling. Normal, unlock, and lock. Od light flashes when I put it in the unlock position just before a pull. Doesn't flash in the normal setting where the pcm has full control of the TC.
I would jump on eBay and find some good strong rare earth magnets for cheap and stick a bunch on your oil pan. Won't catch the brass but anything magnetic that could be floating around. Really makes you wonder about that pump, thing is tore up pretty good.
Friend of mine tried that synthetic rotella once, hated it. Drained it with less than 500 miles on it. I'm running the LE 15-40 in 2 trucks, and have no romp issues.
