Instead of the full set.

Is it possible to install just 1 Defi Gauge i.e Boost.
I assume it will need a control unit and also allow me if required at a later date to add extra gauges.

At the mo I have a cheap boost gauge in a Scoobymania corner dash pod, hence the reason for wanting only a single gauge.

At a later date I may get a triple A-pillar pod as this is the only option for the early dash.

Yes you can use only the single gauge, but you would require the control unit.

Yes you can buy a gauge kit, one gauge and the control unit.

All the sensors plug into the control unit, I think there's 6 or so can run off one box. Once you have the control unit its just a case of buying the gauge/sender packs :D

Worth every penny!

Waht's this likely to cost and is it DIY or only for a professional.

Give Mike @ Scoobymania a call, Hes got them all in stock atm, he will be able to advise you.
