Heavy-Duty Diesel Diagnostics & Tuning
Diesel diagnostics for pickups and heavy-duty trucks: fault codes, sensor and injector checks, regen and DEF system troubleshooting, and legal performance and drivability tuning. We work to keep your truck running strong and working legally.
What it is
Overview
Diagnostics for diesel pickups and commercial trucks, plus tuning that keeps all factory emissions equipment installed and functioning.
Tuning availability depends on legally compliant calibrations existing for your exact engine, year, and region. Many late-model diesels have limited or no compliant tuning options; we'll tell you honestly if yours does.
We do not remove, disable, or bypass emissions equipment (EGR, DPF, DEF/SCR, catalytic converters, O2/NOx sensors), and we do not offer "delete" tunes.

Confirm by VIN/engine before booking.
How it works
The process
- Interview & full scanEngine, transmission, aftertreatment, body.
- Live data reviewFuel rail pressure, boost, EGT, DPF soot/differential pressure, DEF quality/NOx readings, regen history.
- Pinpoint testingAnd, where applicable, service routines (e.g., forced/parked regen, injector or sensor relearns) per manufacturer procedure.
- Tuning (if requested)Verify the truck is healthy and all emissions equipment is present and working first, then install only legally compliant calibrations.
FAQ
Common questions
Do you do delete tunes or remove DPF/EGR/DEF?
No. We don't remove, disable, or bypass emissions equipment. It's illegal and we won't do it.
Why does my truck keep going into limp mode / derate?
Common causes include DEF quality or heater faults, NOx sensor failures, clogged DPF, or EGR problems. We diagnose the root cause.
Can you do a forced regen?
On many trucks, yes, when it's safe and the system is healthy enough to regen.
Is tuning available for my truck?
It depends on whether a compliant calibration exists for your engine and year. We'll confirm before you book.
Do you work on semis and fleet trucks?
Yes, for many engine platforms. Call with the engine make/model.
