Diesel Tuner
Our tuner lineup starts with the H&S Mini Maxx V1 DPF Delete Tuner, a proven programmer for owners running a DPF delete pipe. The updated Mini Maxx Tuner V2 expands coverage to DPF, DEF, and EGR-related calibration needs. Shop by platform with our Duramax Tuner, Cummins Tuner, and Power Stroke Tuner collections to narrow results down to your exact engine.
Tuners Built Around Your Exact Diesel Platform
Diesel tuners are not interchangeable across engine families, and EngineGo organizes this collection so you shop by platform instead of guessing. Ford 6.0L, 6.4L, and 6.7L Power Stroke owners, Ram 6.7L Cummins owners, and GM 6.6L Duramax owners (LMM, LML, and L5P) each have dedicated tuner options built around their specific engine calibration and emissions-related hardware.
Most tuners in this collection pair with a DPF delete pipe, EGR delete kit, or CCV reroute kit, and many are also sold inside full all-in-one delete kits for owners who want the tuner and hardware bundled together. Before ordering, confirm your truck's year, engine, and any prior modifications so the tuner you choose matches the parts already on your truck.
Why Diesel Owners Choose EngineGo for Tuners
A mismatched tuner can trigger codes, drivability issues, or a truck that will not run the way you expect. EngineGo lists tuners by exact platform and pairs each one with the delete hardware it is designed to work alongside, so you are not left guessing what else you need.
Every tuner ships from a U.S. warehouse, with most orders processed the same or next business day. Tuner and electrical products carry stricter return conditions than standard hardware, so our support team is available before you order to confirm the right programmer for your engine, model year, and intended use. That is the fitment-first approach heavy-duty truck owners expect from a diesel-specific supplier instead of a generic parts marketplace.
Complete Your Diesel Build
A tuner works best as part of a complete setup. Pair your programmer with a matching DPF delete pipe, EGR delete kit, or CCV reroute kit for your platform, or shop a bundled all-in-one delete kit that includes the tuner and hardware together.
