The SPADE series (Standalone Programming And Diagnostic Equipment) makes the highest quality tunes on the market available in a simple to use OBD style flash tool. The tunes represent the best in drive-ability, reliability, and power. The SPADE system is the first hardware to ship pre-loaded with tunes of this caliber. No emailing, laptops, or learning curves needed. Each SPADE has the ability to tune up to eight vehicles (with up-charges per each vehicle).

In addition to simplifying the programming process, the SPADE series has the ability to run diagnostics and log data for analysis. In a custom tune refinement situation this logged data can be sent to a DuramaxTuner.com rep to facilitate changes or aid with troubleshooting. Updated tuning files can be sent remotely in the same manner as logged data, making the SPADE tunes field upgradeable.
