Does Ram have a limiter built in to the trucks where you dont got the full potential until you hit 5000 miles? I always thought my truck was a dog compared to my Ram 1500 with the Hemi till this past weekend. I was on the road and thie a**hat in a BMW was cutting in and out of traffic and he keep cutting me off. At a light I got tired of his crap and I just punched it and the truck took off like a animal, I am like wow it never done that before and I was not expecting that. The rear end started to drift right a little, the traction control did not ever seem to kick in, and it was just a nice hard launch. For the rest of the ride down the BMW stayed away because he got dusted by a 7000lb truck. I talk to my friend and he said it's about right. His Challenger 392 did the same thing, at 5000 miles it because a animal.

Now the truck acts like a truck with over 400HP and torq, it is like its allowed to fully run. My truck is completely stock.
 
You’re not the first person to notice this. Others have mentioned it but there’s no real hard data on it.
 
Just went over 5K yesterday. I thought I was imagining it.

I believe it does but no actual data to back it up mine was like a flip of a switch at 6k miles
 
7K miles on mine and it feels the same as the day it drove off the lot, which is a lot stronger than my 18 HO.. which surprised me.
 
I never noticed a difference. I confess though I never mashed the pedal from dead stop, didn't need to it's not a race car I don't pretend like it is.

I guess I can say I’ve never done that on my truck either.
 
Someone is just going to have to dyno their truck right off the lot and then again after 5000mi. I bet they see no change honestly.

Its a very common practice across many manufactures mainly in powersports. I know for a fact Nissan did it with their cummins trucks. I would not be surprised if it was detuned
 
The closest thing to confirmation on the Titan Cummins of a break-in detune was a comment on a TFL YouTube video by a person claiming their boyfriend was a Cummins tech and “knew things”.

Lots of people claim BRP does break-in tunes on their powersports equipment, but again, there’s no confirmation of that from any reliable source.

People have been claiming the same thing about pretty much every engine since computer controls started and as far as I’ve been able to find over the years no one has ever confirmed that such a thing exists either by manufacturer statement or before/after dyno graphs.

If anyone can find hard evidence I’ll happily revise my statement.

Totally agree.

A Dyno would put this all to rest.
