Sinister Diesel - Tuners & Programmers for Duramax
Performance Diesel Tuners for Your GM DuramaxUnlocking the hidden potential from your Duramax diesel has never been easier than with a plug- in performance tuner. Our diesel tuners can be installed in just minutes and give you the highest horsepower and torque gains for your money.
Diesel tuners, including chips, modules, and programmers, all interface with your truck’s on-board engine management computer and modify the stock parameters. Changes to injection timing, boost pressure, and fuel rail pressure then free up hidden power and efficiency from your motor. Not only will you gain more power in lower RPM’s with less downshifting, you’ll also have more complete combustion resulting in more power and torque.
Sinister Diesel stocks chips, modules, and programmers from the top brands including, ATP, ATS Diesel, BD Diesel, Bully Dog, Diablo Sport, Edge Products, PPE, PPEI, and SCT Tuners. Plus we even stock our very own Sinister Diesel Power Package that combines a PPEI Level 1 tune with a Sinister Diesel downpipe-back exhaust and an aFe Power Pro5 intake.
