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.

Any ideas?

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.

Thanks
