I want to get the Defi-Link gauges and the control unit.

To start me off with a boost gauge, do I just need to get the unit and a gauge and somewhere for the gauge to live (A pillar)?

Do I have to get sensors as well as or do the gauges come with the sensors?

Cheers

All you'll need is the control unit and a gauge. The gauge comes with the sensor. A pod also comes with the gauge and can be stuck to the dash. I fitted a set a few months back and found them very easy to fit and I'm very impressed with them.

The boost gauge is also the easiest to fit, due to the sensor being an easy job. Once the control unit is wired in, you could have the boost gauge working in a matter of minutes. :)
