We just ordered a Western Star with a fepto Cummins X15... 565 hp @ 1950 rpm, 2050 lb/ft @ 1150 rpm.
Heard good things and easy to get spark plug upgrade.
Ours will be unregistered on farm/off road.

2012 CCSB Saddle Brown Pearl... DRD tuned
I have 2 brand new 2020 Peterbilt 579's with the new x15@450 hp.
So far my drivers seem to like them and they are definitely a different beast than the ISX15 from a few years before.
The thing that amazed me was the engines we have put out 1550 tq @ 1000 rpm.
I am in Nevada and pulling 110k lbs total around town and getting 7 mpg.
Engines have come a long long way since I started driving big rigs in 1985.

I wish I could find someone to tune my 8.3L ISC in my motorhome!
I wonder if I could shoehorn that QSX in it?!
