The factory boost gauge isn't bad, most of the sending for it units are not accurate. They live a harsh life on the motor.

The origonal electric gauge reads pressure before the throttle body and most mechanical gauges are reading from the intake manifold after the throttle body. There is a difference and it's nice having both.
