The ACERT Cat motors have an off-road/emergency vehicle setting that cranks the power to max and lifts the governors. The shop won't flip that switch for me though, they say it is illegal. I don't know the hours or miles on it, but the age is enough that I wouldn't bother with it.

Actually it is an ecm running change. A complete rewrite of all the operational software. They won't ever consider doing it for an on road truck.
The C-12 cat in the ladder truck I am assigned to is 510hp at 2100 rpm. The engine is governed to 2300. My eyes almost popped out of my head when I first drove it.

OK, so they won't change that parameter when they have the computer hooked up. That better?
The mechanic that told me about it said that at the last company he was at they did it just to see what it would do. And turned it right back down. It was scary.
I don't know what the actual displacement is on a C-12, but I know Detroit would rate the 12.7 up to 500 HP before the 03 emissions hit. Yet this C-15 is only at 475. What a waste of displacement. I would like to know what the 14L Detroit was actually good for pre-emissions.
The setting is for off-road and emergency vehicles, not the limp-home mode.

um,, no not kidding, Just saying,,
I understand what the question was not arguing that it is impressive
and anyone that works in these engines or any others, for that matter Understand that In anything but a truck, Ie marine Industrial,etc knows that these engines in trucks are limited by the actual usable horspower they can make by the amount of actual cooling they have, you put that engine in a evironment that has endless optimum cooling and It can make even More horsepower like the c-16 625 horse cat, in say a marine app, nothing is actually done to the engine to make more power than simply the ecm software (and the obvious marine package ((manifolds turbo cooling etc))
and ther output is from 625 to 1400hp because there cooling is able to keep it at a constant temp wheras a truck cannot,
now if we could just figure out how to make trucks have better cooling like that and be Actually Functional.lol think of the power these things could have!!
at one time I had built a 6v92 that was rated stock at 350 hp, when we were done with it it was running over 630 hp it was in a truck at the time, but that was as much as we could get usable cause we just couldnt keep it cool at anything more than that, and even then it was a challenge man what a power house little buggar that was I loved that truck.

Many years ago I had seen a 1/2 ton step side Chevy truck that had a 6v Detroit in it. I am not sure what model engine it was. He was at Lebanon valley drag way in Lebanon N.Y. He was turning out 9.5 seconds in the 1/4. It blew everyone's mind how fast it was.
