Is it true after 2000 miles our raptor will have more power

And the exhaust sounds much better too, right? It has graduated from a *****?

I don't have any Dyno proof but I can honestly say my WOT pulls from when the truck had 800 miles compared to when the truck had over 2,000 miles (probably 2,500) defiantely had a seat of the pants feel like it had more power. I don't mean just simple break in gains I mean what felt like a decent gain.

I've been watching to see if anyone can confirm this may be something Ford programmed into the PCM

Darin... You’re killing me here.

I realize that the butt-dyno is scientifically proven but more often than not the proof all in our respective hearts or minds.

after some mods and break ins I took one of my bikes for final tuning
- how’s it feel?
me: faster everywhere.

Tuning ensued. I took it back out through a known series of roads to do some more accurate research, came back to the mechanic.

Me: it feels slower.
Mechanic: NFW. you are imagining it. roll it up on the dyno, I’ll prove it to you.

he puts up the before / after dyno runs, overlaying the pre-upgrade power curves - so I had before mods, after mods and break in, no tuning and after mods with tuning showing. 2nd graph was way over the before mods, but had a huge dip in it between 4-7k rpms, and then an almost vertical climb to peak power. after tuning, that dip was gone, and the power curve towered over both previous runs - 10hp almost all the way up, torque was up throughout as well, but once tuned it didn’t “feel” as fast, because once you exited the huge dip in the power curve it felt like God was trying to pull the bike forward and out from under you. With the tuning, the power came on smoothly, less violently and sooner. He did a dyne-simulated drag race between the 2 post upgrade curves and the result were as expected.



Maybe there is value to breaking in the truck motor properly, but scores of horsepower?

That would be an “easer egg” of epic proportions in the automotive world. Not impossible mind you, but I remain skeptical.

If you add two more cylinders it will be faster for sure.
