I don't work for an OEM and I don't need test data to know that the manufactures beak in procedure is soft and is rarely followed to a T. You do you, I'll do me - babying an engine after the first few heat cycles is a waste of time with a roller valvetrain IMHO. Our fuel is junk, the emissions systems actively try to kill the engine and the manufactures are on the hook for everything until the date/mileages is passed; of course they are going to want you to drive the thing like a grandma.Which OEM do you work for? What test data are you basing this on?
Rarely do I blindly appeal to authority, but in this case the manufacturer knows EVERYTHING about the engine's metallurgy and construction, they have tens or even hundreds of thousands of hours of real-world testing and data, and they are the absolutely on the hook for the engine's condition through the warranty period.
The only people I see saying "yeah beat on it to break it in" are the people that are just repeating some BS they read on the internet or they're like "bro I've built 5 engines and I beat on them and they're all great" with absolutely no data on longevity through 60,000+ miles. And I'm sure you can find some racing engine builders that recommend a harsh break in cycle but again, they're not on the hook for 60,000 miles of warranty - the engines they build live a much different life with far fewer miles and hours of life than a manufactured, oem-spec, warrantied, emission-controlled passenger vehicle engine.
I DID wait until 1k miles before I towed with my 19' 6.7 SuperDuty, so there is that. I'm not totally nuts. it's my wife's truck, but I'll be driving it too. I'll do my best to get a blackstone report @1k and we'll compare.
