This X‑2 multifunction unit is a great tool for all horsepower enthusiasts that are upgrading their engine with turbo or supercharger. Following many requests, we came up with a unit that combines boost pressure, air/fuel ratio and a temperature function which can be installed on the cooling system or the intercooler. This meter is made to resist cold temperature, snow, water and dust. The X‑2 meter will give you precious informations to help you pull out more horsepower out of your engine or can save it from bad damages.
