Power increase on the John Deere S660
We here at Alt Tune can increase the power output of the S660 from 320 HP to 380 HP with no adverse effects. The tune will also achieve fuel savings due to being able to run lower gears while doing the same job. By programming the engine ECU to delivery more power the engine load will drop, hence being able to select lower gears. Alt Tune re calibrates factory ECU settings including, injection parameters, torque limiters and other core engine functions. Its a non invasive process is completed via the diagnostic port installed from the factory.
