Duramax Tuners from Sinister Diesel

The factory tuning on most modern diesels limits the horsepower and torque production in favor of longer service life and longer fuel range. But now you can easily let your GM Duramax to live up to its full potential and alter that balance in favor of more power and more enjoyment. You just need a few minutes and basic tools.

Duramax tuners including ECU chips, add-on modules, and plug-in flash programmers all work by changing the stock engine management parameters such as injector pulse width, boost pressure, and fuel rail pressure to get more fuel into the engine where it can produce more power when you need it. You’ll end up with an expanded powerband, fewer downshifts, and more efficient combustion. Not only will your truck be stronger, it’ll be much more enjoyable to drive.
