Speed control

I'd say your motor has set off a code or you have a valet setting somewhere.

Is there a tuner on it? Can't you set the speed limiter on a Diablo tuner?

The diablo tuner can remove the speed limiter. I thought the limiter in general was 98MPH on these trucks?

I thought 112... But either way it's definitly more than 85

Does the 2015 have the "teen driver" setting? Perhaps it's speed limited in there if the vehicle is pre-owned.
