The only time I ran long distance it got 6.8 at 70k with a stwpdeck and running 70-75 across the country.

The problem is the other side of the equation, you can easily be wasting the excess hp.

Don't forget that rated power and peak power are two different things. I am sure Kyle knows this but just something to add to the conversation.
Definitely don't consistently run the Acerts down at 1200 and below. Great way to keep cylinder pressures extremely high and harm the head gasket.

BMEP is a calculated value, though. It is a good measure of theoretical efficiency/performance but at the end of the day it still uses constants and assumptions based on displacement which makes it a so so measure of performance IMO.

Truckers, lets see your rigs!
No sir I’m back in the red truck with a 6nz.
He put another guy in that truck, put me in his truck, and tuned the c-13’s with a 500hp euro tune.

That 12-1300 rpm stuff may be fine dead stock, personally I h8 seeing that. I think your much better off higher rpm with less throttle, like pullin back a gear or 2. Foot buried in it that low is hard on head gaskets and bearings. 
Or you can just put a bunch of power to it and just sail almond and not drop rpm. Lol

This one feels happiest pulling at 17-1800, it lays over pretty fast below 1500 and I think it'd rattle the liners out the bottom at 1200. I don't understand lugging them around all the time.
