File this one under, "jeeeeez". Turbo XS is a tool that allows you to turn your GBA into a "programmable,
upgradeable, automotive performance tool for tuning, data logging, and diagnostics."
The device plugs into your GBA, which then displays a number of diagnostic screens including a Boost Gauge, Exhaust
Gas Temperature Gauge, Air Temperature Gauge and Tachometer. The maker of the device also promises additional
diagnostics in the future.
All sensors are sold separately.
