1)RRP by Defi has remained the same between the old and new BFs. No increase in price between the different gauges.

2)-Control box costs more than the previous model, but as you said, it has better features. I find it quite annoying when my older BF oil pressure meter triggers the warning sound when ignition is turned on before the start up. Obviously, the engine hasn't been started and the oil pressure is at zero, indicating engine failure. Can't turn the warning buzzer off on the old BFs. bummer.

- Also the main control unit now is hidden away with a smaller controller linked to this control box which will be a lot easier to mount on the dash.
