Tuners & Programmers for Cummins - Tuners & Programmers for Cummins
Building a high-performance Cummins diesel engine is hard and tedious work that can cost you more time and money than the performance you’ll get out of it. Consider instead one of the plug-and-play Cummins tuners available from Sinister Diesel.

Cummins Tuners from Sinister Diesel

Getting more performance out of your stock Cummins engine is easier than you think. The tuning done by the factory typically compromises power delivery to make a truck more forgiving to drive and more fuel efficient. But in just a few minutes, you can get back all of the sacrificed horsepower and torque and let your engine live up to its maximum potential.

Cummins tuners (which include ECU chips, plug-in modules, and flash programmers) all give you more power by altering the factory tuning parameters used in the stock engine tune. This changes things like injector pulse width, turbo boost pressure, and fuel rail pressure allowing your Cummins to get more fuel and air into the engine to deliver even more power when you need it. You’ll get a wider powerband, fewer downshifts, and more efficient combustion. In just a few minutes, it’ll feel like a brand new truck.
