A modification is not automatically good or bad. Buyers need to know what changed, why, who performed the work and how it affects safety, legality, serviceability and warranty.
Document every change
Ask for parts, software, installer invoices and the original components where available. Unknown tuning or undocumented wiring increases uncertainty.
Keep emissions disclosure neutral
Confirm factory emissions equipment is present and functioning. DieselTrucks.ca does not encourage tampering; buyers should verify applicable requirements for their jurisdiction.
Inspect the surrounding truck
Power changes can affect transmission, cooling, driveline, tires and brakes. Have a qualified technician assess the complete build.
