Duramax Tuner Spade Series King (2001-2007 GM 6.6L Duramax)


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). Emissions intact only. For vehicles with all factory emissions systems. 


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 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.
