Economy files show no new power figure because they are written for torque and drivability rather than peak output.

Remapping the 14.6 481hp (354kW) 2380Nm

The Caterpillar 3406E All years 14.6 481hp (354kW) 2380Nm runs a factory calibration built to cope with poor fuel, skipped servicing and hot countries. We rewrite the fuelling, boost and timing for this engine on this car, then test it before you get it back. The original file is kept, so it can go back to standard whenever you want.

On the petrol side the difference shows in throttle response and in how hard it pulls through the top half of the rev range. It feels sharper off idle and keeps going where it used to flatten out.

Figures on this page are for a standard car in good health. We read the fault codes and check the basics first, and if something needs attention we will tell you before we write anything. Have a look at the other engines on the All years, the full 3406E range, or everything we do for Caterpillar.
