Hi
I just installed my device custom 87 octane tune. When I start the truck everything is fine. After driving it for a little bit the brake light comes on and it syas brake service. I stop and shut the truck off and restart it goes away. Can anyone help me with this?

Thanks

did you change/adjust the tire size in the tune when you installed it?

Yes I had to change it to my 35" s.
