I have a 2016 2500 with wARP tunes by Ray.
These tunes were done way back in 2016.
However recently my actuator failed and I upgraded to a A300 last week.
Now the truck is surging when I give it throttle, and p2580 (turbocharger speed sensor circuit low) persists.
I have added a BD exhaust brake but until I get a couple needed parts the brake has the fuse pulled, and have not been able to use it.
Am I screwing up having the exhaust brake plugged in but the power killed to it?
Do I need more tuning?
Should the turbocharger speed sensor be plugged in and tied up, or removed?
My apologies for the questions, I'm just not having much luck reading on it.
