Liberty Diesel pull truck under full load on the dirt track
Tuning

Your truck was tunedfor someone else.

It left the factory calibrated for emissions compliance and a stranger's idea of average use. Tuning is how you make it work for your truck, your load and your fuel bill - with monitoring so you can prove it worked.

Why tune it

Four reasons a diesel owner tunes.

Nothing here is about chasing a number on a dyno sheet. It is about fuel, smoke, load and longevity - the things that decide whether the truck earns.

Fuel efficiency

A stock calibration is written to a wide safety margin, not to the load on your truck. A proper tune cleans up the cruise-range fuel map so a working truck stops paying for fuel it never burns.

Better emissions

Correct injection timing and atomisation burn the charge more completely - less visible smoke, cleaner regeneration cycles, and a truck that behaves itself at inspection.

Offroad capability

For track and competition use, tuning is where throttle response, boost control and torque management are set up for the sled instead of the school run.

Truck longevity

Managed rail pressure and torque limits protect the parts you already paid for. A correct tune is cheaper than the transmission it stops you from cooking.

How it works

Three steps, no guesswork.

01 - Plug in

The AutoAgent 3 goes into your OBD-II port and powers itself from the truck. No wiring, no permanent install.

02 - Connect

It broadcasts its own Wi-Fi hotspot. Pair the Auto Agent app and you are talking to your truck in a minute.

03 - Load and watch

Load the tune, then use the logging to see exactly what changed - fuel, boost, temperatures and codes.
