Collection: 2007.5-2009 Cummins 6.7L

This is where 6.7L Cummins tuning started—and where you’ll find the right tools to make it run the way it should. Our 2007.5–2009 Cummins 6.7L tuning kits and performance parts are built for owners who want real files, tested hardware, and no guesswork.

The early 6.7L platform came with challenges—throttle lag, heat issues, and limited tuning support out of the box. But we’ve built tuning kits that fix all that. Whether you’re running a 2008 Ram 2500 or a 2009 3500, our custom files and bolt-on parts give you calibrated drivability and smoother performance without cutting corners.

You’ll find:

• DIESELR custom tuning files delivered for EZ Lynk, Commander, and SCT
• Tuners that don’t require ECM shipping
• Transmission calibration with higher-level tunes
• EGR and exhaust support hardware that installs clean
• Complete All-In-One Kits for those who want it done right the first time

Each product in this collection is tested on real trucks—not just listed because it fits on paper. Our tune files are matched to your engine, transmission, and intended use. Whether you’re towing heavy or keeping it street-safe, we’ve got the file to back it up.

No generic maps. No parts bin bundles. Just real 2007.5–2009 Cummins 6.7L tuning kits that get the job done and make your truck drive like it should have from the factory.
