Performance Diesel Tuners Accessories for Your Dodge Cummins

Getting extra performance from your Cummins diesel has never been simpler than with a plug- in performance tuner. Our diesel tuners give you the most performance gains per dollar of any modification and can be installed in mere minutes with basic tools.

Diesel tuners, including chips, modules, and programmers, interface with your truck’s on-board computer, then modify the stock fuel injection parameters to unleash up hidden horsepower and more torque. Not only will you have more power in higher gear and less downshifting, you’ll also have more complete combustion and better fuel economy in the long run.

Sinister Diesel carries chips, modules, and programmers from the top brands including, aFe Power, ATP, ATS Diesel, BD Diesel, Bully Dog, Diablo Sport, Edge Products, PPEI, and Smarty. Plus we even stock our very own Sinister Diesel Power Package that combines a Smarty SR Programmer with a Sinister Diesel 5in stainless steel exhaust kit and an aFe Power Pro5 intake.
