Those that have tuned or programmed

^^^I bet if you were to ever climb a long 6 or 7% grade at 60 mph, on a hot day with that 4020 you'd watch your gauges very close. In a situation like that, would you have to back off to prevent overheating or would your programmer defuel for you?

If my temps were getting hot then I would defuel myself while my father-in-laws stock F350 will do it on its own. There are limiter built into my tuning files that, but I back it down before they are reached. Although I am not sure what the point is here since I have already stated that the various power levels I use are based on the load and temps I am at just like the stock engines. Are you not reading what I am posting? I would also ask what is the point putting my truck in a scenario it will likely never be in because I would have went with a different truck set up (like a 4.10 DRW HO) if that were the case?

The main difference is that I can sustain higher power levels than stock since I have mods that can support higher power levels and reduce how much heat the cooling system has to shed versus stock. My coolant system does not have to keep an EGR cooler and turbo actuator cool on top of keeping the engine cool. My intake is set up in a way to keep temps 10% lower than stock, and there hardly any resistance pressure in my 5" exhaust. This is essentially the same setup that my hot shot friends use on the DRW HO's that allows them to keep it at 425 hp at the wheels towing much heavier weights than I am on a regular basis.
