Quite the contrary, that is actually very true. Race car and bike operators are always looking to squeeze the last drop of horsepower out of an engine, and if 500-1000 miles of gentle run-in on a dyno made 20 extra HP on a 900 HP engine, you can bet they'd do it. But it doesn't. A systematic method of high-load acceleration followed by engine braking usually yields the tightest, and longest-lasting engine possible.

And I know for a fact that stronger engines, all other factors aside, get better mpg when driven easy.

Ah, OK. So some super focused driving with load (DWL) / "target" driving. Nice work.

No opportunities to pull off to let following traffic by you? I did that a few times on my weekend trip where I was DWL as well. When I see someone coming up in my rear view, I start looking for opportunities ahead where I can let them by. The only frustrating thing is getting someone on my bumper who for whatever reason *won't* take an opportunity to pass even when it's clear sailing.
