xTra Gold Box


The MS3 Gold Box is a powerful, feature packed engine management system that the budget minded enthusiast has been waiting for. The Xtra Gold Box gives us the ability to provide our customers with either integrated transmission control (GM 4L60/4L80)  or an I/O extender (8’ flying lead)  for those of you who can’t get enough data. Our Gold Box plug and play systems have become very popular, but many of our customers are requesting a universal system. Now they can harness the awesome power of the Gold Box for applications we do not offer a custom harness for. Whether you have a passion for street, race or show cars, the Gold Box gives you exactly what you need. Please use the configurator below the build your Xtra Gold Box to suit your needs!
