Driving under almost constant Boost (towing) hard on the engine?

[JCT]

that's just baja mode

Where are you in Europe? I saw a number of Raptors around Como last Spring.

I wouldn't worry about it. As someone mentioned earlier, just watch the temps closely.

In the long run, the turbos will complain about it more than the engine will.

No, As @New recaros said low boost isn't an issue long term.

My '23's, on a 5000 mile road trip pulling a camper, 8-9mpg, oil change meter told me oil change required before I even hit 5000 miles. My typical driving oil change meter would be about every 10k miles, I normally change it every 5k full synth. I had changed my oil a couple days before this trip and right after getting back. With frequent camper trips, I would step up your oil change interval accordingly.

My 21 was in boost at 75 mph on the Interstate. So, some of you are saying driving down the interstate at 75-85 mph I am going to blow-up the turbo’s or cause excessive wear in engine?
You guy’s smokin crack or just blowin stuff out the crack?

All other things equal- it will die quicker running under boost than not.

Everything is stressed more when it's in boost.

The fuel system, the main and rod bearings, the piston rings- all of it's worked harder, and you get more blowby into the oil.

Will it kill it tomoroow? No.

Will it make the difference betwen the engine living 250K miles vs 200K miles? Maybe.

Do you have a choice in the matter? No, other than frequent oil changes to help with the blowby issue.

It's fine, it what they were engineered to handle.
Now, adding a tune throws all that out.

Just watch your temps. There are design factors built in. Towing was taken into account.
