I was fortunate in a way. When I bought my 7.3, my BIL was a director at Ford SVO in Dearborn (he's since advanced a bit) and he 'borrowed' my new truck for a month. It spent a month in Dearborn and I didn't ask what it was doing but it accumulated 1000 miles in a month.
When I got it back it came with a bunch of goodies installed. Limited slip axles front and rear (Detroit Tru-Trak in the back, ARB Air Locker in the front), full Banks kit with full delete exhaust, B&M prototype deep sump trans pan, complete transmission rebuild with heavy duty internals and 2 huge Hayden transmission coolers..and appropriate gauges too. No charge. I never look a gift horse in the mouth..... Were a bit hard on the tires but what the heck, tires are expendable.
I agree, with any diesel, especially one with increased fuel delivery like mine, EGT and transmission temp monitoring is paramount. I can pull upwards of 30 pounds of boost if I work it hard but I always watch exhaust temps and transmission temps.
I very seldom get on it. I know it's there but why abuse it. Hauls my camper around just fine. Gets good mileage too.
