Related questions about Cummins QSC All Years Delete DPF EGR DEF SCR

Can you delete DPF but keep EGR?

Yes, it is possible to delete the DPF and retain the EGR system on a Cummins engine. This method allows for some emissions control while still enhancing performance. However, it's essential to evaluate the overall engine performance and emissions compliance after such modifications.

Do you need a tune after EGR delete 6.7 Cummins?

After performing an EGR delete on a 6.7 Cummins engine, a tune is generally required. This tuning process ensures that the engine runs efficiently without the EGR system, optimizing performance and preventing possible damage from running without the necessary adjustments.

Why delete EGR on 6.7 Cummins?

The primary reasons for deleting the EGR on a 6.7 Cummins include enhancing performance, improving fuel efficiency, and reducing the likelihood of engine issues caused by EGR system failures. Many users report significant improvements in engine responsiveness after this modification.

How much HP does a DEF delete add?

A DEF delete can potentially add around 20-40 horsepower, depending on the specific engine and tuning setup. This increase in power is due to the removal of restrictions imposed by the DEF system, allowing the engine to operate more freely.
