What's the difference between autocal and bench flash tuning?

Autocal tuners (like EZ LYNK and Iron Loader) plug into your OBD-II port and reprogram your PCM wirelessly. You can swap tunes between vehicles. Bench flash requires removing your engine control module and flashing it with new code—it's more involved but allows deeper customization. Autocal is faster and more convenient; bench flash gives you more control.

Will delete tuning void my warranty?

Yes. Any emissions delete tuning voids your factory warranty. That's why these products are sold for off-road and competition use only. Your dealer will see the tune when they scan your truck.

Can I switch back to stock tune with these tuners?

It depends. Most autocal platforms let you save your stock tune before deleting, so you can revert if needed. Bench flash is permanent unless you have another flash file saved. Always back up your stock tune before any modifications.

Do I need to delete my DPF physically if I'm tuning it out?

Not always. A delete tune removes the DPF function from your PCM, but the physical filter stays on your truck. Some guys remove it for weight savings and airflow; others leave it in place. Check your local laws—some areas require the filter to stay installed even if it's disabled.

Which delete tune is best for towing?

The 6.7L Cummins handles delete tuning well for towing. EZ LYNK and EFI Live both offer conservative tune maps that add power without sacrificing reliability. Start with a stock or mild tune if you're regularly pulling heavy loads, then adjust from there.

How much horsepower will I gain?

Expect 50-100 hp and 100-150 lb-ft torque depending on your engine and tune aggressiveness. The 6.7L Cummins responds better to deletes than the EcoDiesel, but both engines see measurable gains. Actual results vary based on your truck's condition and driving habits.

Is delete tuning legal on public roads?

No. Federal and state emissions laws prohibit driving deleted diesels on public roads. These tunes are strictly for off-road, track, and competition use. Running a deleted truck on the street can result in heavy fines.
