Cummins EGR, DPF, SCRAdBlue Delete Solutions – Tested & Proven ECU Tuning Services
If you've worked with Cummins-powered trucks, agricultural machines, or industrial equipment, you’ve likely dealt with emissions systems like EGR, SCR/AdBlue, and DPF. These components are designed to meet regulations but often lead to reduced performance, increased maintenance, and higher operating costs.
Since 2015, we've specialized in helping businesses and operators across the globe get more reliability and performance from their Cummins engines through tested, safe, and complete emissions system removal.

Why Remove EGR, DPF, and SCR/AdBlue?
These systems were made to reduce emissions, but they often bring extra headaches:
- DPF clogging
- AdBlue consumption issues
- EGR valve failures
- Frequent forced regens and downtime
⚠️ Important: Don't Mix and Match Deletes
Some folks ask to remove just the DPF while leaving the AdBlue system intact. That’s a shortcut we don’t recommend—and won’t support.
Why?
Because SCR/AdBlue systems rely on NOx sensor feedback. If you pull the DPF and keep SCR running, it’ll throw errors and eventually shut the system down. Always delete them together or just remove AdBlue and keep DPF/DOC active.
We do things right the first time.

Know Your Cummins Engine
Here’s a quick breakdown to identify what you’re working with:
Displacement Groups:
- Midrange: under 9L (ISB, ISC, QSB)
- Heavy-Duty: 10–15L (ISX, QSX)
- High HP: 19L+ (QSK, QST)
- "IS" = Automotive use
- "QS" = Industrial
- Suffixes like "TA" = Turbocharged Aftercooled
- Letters like A, C, G = Application (Agriculture, Construction, Generator)
