Diesel DPF, DEF & SCR delete tuning
Diesel tuning for trucks, agricultural vehicles and construction equipment.
K2 handles enquiries for DPF, SCR, DEF and EGR emissions-system delete tuning. Share your engine details and existing setup to discuss the requested service.

Diesel trucks
Send the truck’s year, make, model and engine, along with its current emissions-system configuration.
Agricultural equipment
Include the equipment model, engine and current calibration or modification history where known.
Construction equipment
Describe the machine, its engine and the tuning work you want to discuss.
Check the rules before modifying
Emissions-system modifications may be restricted or unlawful depending on vehicle use and jurisdiction. Off-road use alone does not establish legality. Confirm the requirements that apply to your vehicle before proceeding.
Give the enquiry a clear starting point.
Include the details you know. If something is uncertain, say so rather than guessing.
Vehicle details to send
- Year, make and model
- Engine and transmission, where known
- Existing hardware and software modifications
- Current issues, warning lights or fault codes
- The service you want and your intended use
- Previous calibration information, if available
Before you enquire
Send your vehicle’s year, make, model and engine, along with existing modifications, current concerns and the service you want. Include transmission details and previous tune information if you have them.
No. Calibration verification is for a vehicle that has already been deleted and needs its existing calibration verified. A performance enquiry concerns changes such as horsepower upgrades, sound-focused tunes or transmission tuning.
No universal compatibility is claimed. Share your vehicle and hardware details with K2 to discuss the requested service rather than assuming a listed tune applies to your setup.
Off-road use does not automatically make an emissions modification legal. Restrictions depend on the jurisdiction, vehicle and use. Confirm the requirements that apply before proceeding; a tuning service or calibration check is not proof of compliance.
