Delete & performance tuners for diesel trucks
DPF delete tuners apply a calibrated flash that matches your aftertreatment state and disables forced regen commands, with DEF and EGR delete logic where required, plus DTC control for related tests. OBD-II or bench-flash workflows with logging for EGT, boost, rail pressure, and soot/regeneration PIDs help validate towing loads and axle-ratio or tire-size changes.
Fitment coverage:
-
Ford Powerstroke (3.0L, 6.0L, 6.4L, 6.7L)
-
Ram Cummins / Dodge Ram (6.7L)
-
GM Duramax (LML, L5P, LB7, LLY, LBZ, LMM, LM2, LWN)
-
EcoDiesel (Jeep Grand Cherokee 3.0L, Ram 1500, Jeep Wrangler & Gladiator 3.0L)
-
Mercedes Sprinter (3.0L)
Technical specifications and system features
-
Flash access path: OBD-II write, bench flash or ECM exchange based on diesel platform and ECU generation.
-
Logging scope: EGT (°F), boost (psi), rail pressure, and regen/soot status to confirm the setup after install.
-
Calibration behavior: disables regen targets (~1,000–1,200°F EGT) and controls DTC logic tied to DPF/DEF/EGR monitors.
-
Hardware interface: vehicle-specific cables/connectors and stable 12–14V power support to avoid interrupted writes.
-
Update and licensing: VIN-tied activation where used, plus firmware or update files to reduce mismatched calibrations across trucks.

-
Support components: ECU/ECM unlock tools, unlocked ECM/TCM units, SOTF switches, cables, pyrometer (EGT) sensor + docking station.
How to choose the right diesel tuner
-
Confirm exact fitment: match model year, engine, and ECU/TCM family; don’t average year ranges.
-
Pick the workflow: OBD-II flash vs bench flash vs unlock/exchange requirement.
-
Verify tune scope: DPF/DEF/EGR delete, plus tire/gear corrections if needed.
-
Check licensing + support: VIN-tied rules, update path, and whether log review is available.
If you’re unsure, contact our support to match the right diesel delete tuner to your ECU/TCM and required workflow before purchase.
FAQs
Yes. After a DPF delete, the ECU will still run soot loading logic and command regen without a tuner, typically driving EGT toward ~1,000-1,200°F during active regen events. A delete tuner updates DPF-related tests, DTC strategy, and regen triggers to match the new exhaust state. Off-road use only applies where emissions equipment is removed.
You usually get a check engine light with error codes plus regen attempts with no DPF present, which can force high EGT cycles and limp/derate behavior on some calibrations. Common outcomes include stored DPF/soot DTCs, failed readiness checks, and unstable fueling during regen commands. Fix is a correct delete tuner file for your exact ECU and year range.
You can load a DPF delete tune and related DEF/EGR delete calibration using the following devices:
- EFI Live AutoCal V3: GM Duramax and Ram Cummins custom file loading + detailed datalogging.
- EZ Lynk Auto Agent 3: supported platforms with app-based logging and remote file delivery.
- Mini Maxx V2/H&S Mini Maxx V1: supported applications with on-screen gauges and selectable power levels.
Sometimes. If your ECU is locked, you’ll need a bench unlock, an ECU unlock tool, or an ECM exchange before flashing the final file. A safe write depends on stable voltage (keep the truck at ~12–14V during flash) and using the correct cable/interface for your ECU family.
Choose by workflow and the data you need:
- Want detailed logs for boost, rail pressure, EGT, and regen PIDs: EFI Live AutoCal V3 or EZ Lynk Auto Agent 3. Suitable for Ford Powerstroke, GM Duramax and Ram Cummins.
- Real-time EGT monitoring for in-cab pyrometer displays - essential for heavy towing and performance driving. Monitor exhaust gas temperatures and keep your engine operating within safe limits under sustained load. Supported devices: Mini Maxx V2, H&S Mini Maxx, EZ Lynk Auto Agent 3. Compatible with Ram Cummins and Ford Powerstroke platforms.
- OBD-II flash tuning for Ford Powerstroke engines via the diagnostic port. Quick and direct ECM calibration using the Bully Dog BDX tuner.
SOTF (shift-on-the-fly) lets you adjust power levels while the engine is running, commonly 3–5 positions depending on files and hardware. SOTF is commonly supported on platforms using EFI Live or EZ Lynk DPF delete programmers. It requires compatible tune files plus the correct switches/cables for your specific Ram Cummins or Ford Powerstroke listing. Don’t assume cross-compatibility between year ranges.
Typical wheel gains vary by vehicle turbo health, fueling, and file type:
- Tow file: +30-60 HP, +80-200 lb-ft.
- Street file: +60-120 HP, +150-300 lb-ft.
- Aggressive file: +120-180 HP, +250-400 lb-ft.
Validate with logs: boost (psi), EGT (°F), and rail pressure behavior under load.
