My truck is a 2000 Ford F250 7.3 motor with over 207,000mi still operating with excellent power. I ran a superchip which has 2 programs, trailer tow safe & high performance, for quite a while, but it was in my opinion disguising its stock performance. After removing the performance chip, I found most sensors involved were not doing the job they were intended to do, high mileage. Last year I launched boat at a lake that has a very long & steep ramp, low lake level. When adjusting trailer to water I hardly had any power to crawl up 10 feet, this was the start of troubleshooting of the power loss. To start with found exhaust back pressure line clogged & cracked, as seen in pics-a common problem with 7.3, sensor it was connected to was completely clogged. Other sensors changed IPR-injector pressure regulator, ICP-injector control pressure, MAP sensor, Air intake temperature sensor just to name some critical components. About 6yrs ago, I replaced the turbo with a slight upgrade new turbo, this was a good power move ruling out any turbo issue, inner cooler boots to turbo had signs of leakage (see below), replaced.
