2022 x15 Cummins new Gen

The lack of power is ridiculous In autos. I had to drive an x15 earlier this year. The 500 horses was just as gutless as the mx13 at 455.

 

There's different shift calibrations for these Endurant transmissions if that's what it was using. Most companies out there keep them in Standard Mode with the belief that they'll attain better fuel mileage lol. My money is on it being in an economy or standard mode.

 

I don't think it can handle anything higher.

It had some work done to it 2 weeks ago. The truck was peppier and more responsive. Unfortunately. The clutch started slipping when I activated cruise control.

It's back to its stock power and no more slipping.

The clutch was replaced 3 months ago.
