1. The 5-6 bars should realistic be set on the road, but it will be close if your car uses the full duty cycle of fuel injector.

2. The "B" led indicates the flow is inside the failsafe window after system activation. If you set the WL and WH correctly. The "B" led should stay on during water spray.

3. I suggest disconnecting the boost until the failsafe window is set correctly. You will never get the same reading with the boost cut in circuit.

Your aim is to have a sustainable "B" led during your WOT runs.
