Exhaust Back Pressure

Whats a normal Exhaust Back Pressure. I have 20.5 psi at idle, and 23 or so running down the road.

Unplug it and don't worry about it. That should eliminate your code.

Is your gauge go off the factory sensor, or is it mechnical. If its mechanical it would show only about what boost is. If your ebpv is sticking completely closed it would show 15 to 20 at idle. about 40 at highway speeds if your can get there.
