Boost and performance data on your dashboard display!


GoodBox allows you to convert your Mazda RX8, MAZDASPEED 3 or 6 digital OEM dash into a read-out of your car’s computer. Why pay for gauges that simply clutter your interior when GOODbox can save you space and money? GoodBox is an elegant way to track your boost, if you have a turbo-charged or super-charged Mazda. How cool is it to monitor your mods from your dashboard as you are driving your car? Even if your car it totally stock, it’s still awesome to see how it is performing in real time. No worries about toggling back to your normal readout, just push a button and you are back to your car’s OEM default settings.
