1200+ hp / 2100+ lbs-ft

I bet the new ones are not' daily drivers' in any area with emissions testing. None of them have any emission mandated controls.

Fun to watch but I have no desire to own one. My old 7.3 puts 350 to the rear wheels and 650 pounds feet of torque with OD locked out. Plenty enough for me. Gets 18 on the road too.

I'd never install an aftermarket tuner because advancing the injection point on any diesel stressing the internals way too much for reliability.

When you start fueling a Tier 4 compliant motor, all that soot has to be consumed by the SCR and the DPF and that shortens their life span as well.

Finally, at 68, I'm too old for that nonsense.

Well to each their own, but just because you don't want to modify your truck(which you have) doesn't mean you should rag on those that do. Just because 350 rwhp is plenty enough for you doesn't mean you should ask someone else why they would want more in their truck.

Although I do not think you know exactly how the new emissions work. The SCR does not consume soot. It converts NOx into nitrogen and water vapor by injecting DEF. The more NOx is created(more power), the more DEF it injects. The DPF collects soot which is before the SCR.

Also, with today's VG turbo's, multi-injection injectors, and high fuel pressures you would really have to be pushing things or just purposely dumping fuel to create a lot of soot. Older fixed geometry turbos and big aftermarket turbos create a lot of smoke, because they take time to catch up with the amount of fuel being pumped in. With modern VG turbos and good mapping, you can run much higher power levels without creating nearly the amount of soot.

Lastly, you can advance timing without causing "stressing the internals way too much for reliability". As with anything, there is a right way and a wrong way. Too much timing at the wrong rpm causing high cylinder pressures at low rpm puts a lot of stress on engine internals. At higher rpms, not so much.

I know many oil field hot shotters running tuned with well over 400k on their trucks. Hell, even my Dad's 99 7.3L with over 300k on it has been tuned since 50k while my father in laws 6.0L with over 350k has been tuned since it came out of warranty. Saying that adding a tuner stresses internals too much for reliability is just an ignorant statement. Like I said, a right way and a wrong way.

But again, just because you don't want to doesn't mean you should go out of your way to rag on those that do.
