MADS Smarty Tuner - 6.7 Cummins ('07-'09)

Smarty is hands-down the best plug-and-play tuning platform for the 6.7 Cummins. The S67 tuner sits in-between the Smarty Jr and Smarty Touch tuners. It offers the same capabilities as the Jr but also allows for custom tuning and comes with more preloaded tunes. Additionally, it has all the same features and functionality of the Smarty Touch tuner minus the fancy touch screen display. The S67 is a good in between device for those looking for custom tuning capabilities but not needing the touch screen, especially if opting for an Insight CTS3 instead.

The S67 comes preloaded with 8 different canned tunes, ranging from +30hp to +170hp. It has a built-in DTC code reader, is adjustable for different tire sizes, and has various programmable parameters for more advanced tuning control. 

Smarty S67 Benefits:

• -8 preloaded tunes (+30hp, +60hp, +90hp, +130hp, +170hp)
  • -Option for added timing or no added timing
• -Built in DTC code reader
• -2-5mpg fuel economy gains
• -Easy installation
• -Customizable parameters for more tuning control
• -Programmable speed limiter
• -ABS and speedometer calibration
• -Quick ECM flashes (less than 5 minutes)

Overall, this is the best option for the 6.7 Cummins for people who need more customization than the Smarty Jr offers but either don't care about the touch screen, or are using a tuner in conjunction with a CTS3.

Please note we do not currently have the S67 available for 2010-2012 models.
