2015 Cascadia changing to performance mode

Not sure how it works in a Freightliner, but I used to drive a Mack that had performance mode. It was just a simple button on the shift pad to activate. It would allow higher revs in each gear and eliminate those stupid "skip shifts" that every auto seems to do. It worked great in the Mack, I used it all the time.

It will kill your MPG's though, if that matters.

 

My 19 freightshaker has performance mode on the auto shift. Still worthless like every autoshift. As for why truck will not go faster than 65, is its speed limited electronically.

 

The speedlimit is a parameter that needs to be adjusted. If this is a fleet truck, then this is set by your organization. Otherwise, you can adjust these for max roadspeed.

 

DDL program to allow Performance mode and set speed limiter. There's a ton of things that can be changed/altered so it's best to have a competent person adjusting the settings.

 

Agreed. If this is unfamiliar to you, then I would take it to an individual who is capable and knows what they are doing.
