How work?
The 2019, 2020, 2021 6.7 Cummins delete kit w/ EFI Live AutoCal V3 tuner combines physical emissions-system removal with vehicle-specific engine tuning. The selected pipe or complete exhaust replaces the factory DPF and DEF/SCR aftertreatment section, while the EGR kit removes the valve and cooler. EFI Live then loads the matching calibration so the engine no longer commands factory regeneration or monitors the removed emission components. The result is a complete All-in-One bundle that reduces exhaust restriction and soot recirculation while providing selectable performance settings.
Features
A key feature of this 6.7 RAM Cummins delete kit is custom EFI Live tuning rather than a generic preloaded file. AutoCal V3 acts as the delivery and diagnostic device, while the actual tune is prepared around the truck’s year, engine, transmission, and configuration.
Pickup applications support SOTF power changes, allowing the driver to switch between supported levels without performing a complete ECM reflash each time. Optional transmission tuning can also match the engine upgrade to compatible 68RFE or AISIN applications.
The standard package does not list a CCV modification among the supplied parts, so CCV upgrades should be treated separately.
Tuning & Settings
The 6.7 Cummins delete kit has two confirmed tuning configurations.
| Configuration | Available Power Levels |
| Engine Tune / No TCM | Stock / +30 / +65 / +100 / +130 HP |
| With Supported TCM Tuning | +30 / +60 / +90 / +120 / +150 HP |
These supplier-specific level sets are both confirmed in the current technical database and should not be merged into one generic five-level range.
| Characteristic | Typical Result |
| Fuel Economy | Approximately 5-10% potential improvement under comparable driving conditions |
| Power | Up to +130 HP without TCM or +150 HP in the supported TCM configuration |
| Torque / Response | Stronger usable torque and improved throttle response depending on selected tune |
| Exhaust Flow | Reduced restriction after removal of the factory DPF/DEF aftertreatment |
| Regeneration | Factory DPF regeneration is no longer commanded with the correct hardware and tune |
| Towing | Improved response under load; factory towing and axle ratings remain unchanged |
A 5-10% economy improvement is also the published estimate for this matching EFI Live package, but actual efficiency depends on tune level, tires, gearing, payload, maintenance, and driving style.
Optional Add-Ons
- No TCM Tune – engine calibration only; use when transmission tuning is not required.
- 68RFE TCM Tune – transmission-specific calibration for compatible 68RFE trucks.
- AISIN TCM Tune – selectable transmission calibration for compatible AISIN-equipped trucks.
- 4-Inch Exhaust System – high-flow replacement system with a more moderate exhaust size and sound.
- 5-Inch Exhaust System – larger-diameter option with a deeper, more aggressive tone.
- Delete Pipe – replaces the factory aftertreatment section while retaining more of the original exhaust.
- With Muffler / No Muffler – choose quieter operation or a more direct exhaust sound.
The product’s stored variants include combinations of None, 68RFE and AISIN with all three exhaust choices and both muffler configurations.
Key Benefits
Vehicle-Specific EFI Live Tuning – calibration is prepared for the actual truck rather than supplied as one universal file.
SOTF Power Control – supported Pickup tuning provides multiple selectable performance settings.
Transmission Options – compatible 68RFE and AISIN configurations allow the engine and transmission calibration to be matched.
Reduced Exhaust Restriction – removal of the DPF/DEF aftertreatment provides a more direct exhaust path and can improve boost response.
Complete Hardware Package – tuner, custom files, EGR components, and selected exhaust parts are combined into one package.
Installation Information
Installation instructions are available with the product. A mechanically experienced owner can complete the hardware work using metric sockets and wrenches, extensions, penetrating oil, coolant drain equipment, an exhaust sensor socket, torque wrench, and a lift or properly rated jack stands.
Prepare the correct EFI Live calibration before removing the factory emissions hardware. EFI Live setup requires a Windows computer for file transfer and device configuration. An experienced installer should allow about 3-5 hours for a full exhaust, EGR removal, and tuning installation; a simpler Delete Pipe configuration can take less.
Once AutoCal is configured and the tune file is loaded, EFI Live states that vehicle read/flash operations can take roughly 30 seconds to 7 minutes, depending on the vehicle. Additional time is required for initial software setup and tune-file preparation.
No More Emissions Codes
Correct hardware removal and matching EFI Live tuning prevent supported warnings and derate requests caused specifically by the removed DPF, DEF/SCR, and EGR systems. Normal diagnostics remain available for unrelated engine, fuel, turbo, transmission, wiring, and sensor problems.
Common applicable code families include:
- DPF: P2002, P242F, P2452, P2453, P2458, P2459, P2463, P246C
- EGR: P0401, P0402, P0404, P0405, P0406
- DEF/SCR: P203B, P204F, P205B, P207F, P208A, P20B9, P20BA, P20EE, P229F, P249D
Exact code coverage depends on the vehicle-specific calibration supplied for the truck.
FAQ
The best configuration depends on the truck, but the delete kit for 6.7 Cummins 2019, 2020, 2021 combines vehicle-specific EFI Live tuning, EGR hardware, exhaust choices, and applicable transmission options in one package. That reduces the need to source and match major components separately.
EFI Live AutoCal V3 supports custom vehicle-specific tune delivery, SOTF operation, data logging, diagnostic functions, and future tune-file revisions from the calibration provider. It is a tuning interface rather than a generic one-file-fits-all device.
Yes. Engine-only configurations support levels through +130 HP, while supported TCM configurations can provide settings through +150 HP. Actual output varies with the selected tune and the mechanical condition of the truck.
A properly maintained truck may see around 5-10% better fuel economy under comparable driving conditions after reducing exhaust restriction and eliminating active regeneration. Aggressive tuning, towing, tire size, idle time, and driving style can reduce or eliminate that gain.
A capable DIY installer with normal diesel mechanical experience can complete the project. Exhaust work is relatively straightforward, while EGR cooler removal, coolant routing, EFI Live setup, and optional transmission tuning require more care. If those procedures are unfamiliar, installation by a diesel performance shop is recommended.

Everything arrived quickly. Before ordering, I called with questions and was relieved to talk to someone who actually knew the products. The tune loaded in minutes. Exhaust install was manageable solo. Haven’t done the EGR yet, but based on everything so far, I’m confident it will go smoothly. The truck feels renewed.
Finally wrapped up the full delete and couldn’t be more pleased. Even in sub-zero temps, the truck runs like a rocket.
Package arrived secure and complete. Instructions and videos were easy to follow, though a couple of small steps were missing. Still ended up being an easy project overall. Power increase is huge, and the mpg bump makes it even better.
Purchased the EZ Lynk delete bundle with muffler and throttle valve delete. Installation was manageable even as a novice. The truck now responds better, pulls harder, and delivers improved highway MPG on the 80 HP tune.
Thanks to Adrian for answering my questions before purchase. Ordered Saturday and had all parts by Wednesday. Install was straightforward, hardest part was removing the factory components. Support chat was fast and helpful throughout.
