Remapping the 6520 6.8 110hp (81kW) 510Nm
The John Deere 6020 Series (2001 >) All years 6520 6.8 110hp (81kW) 510Nm 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.
