The handling work in intensive applications needs a big consumption of fuel and has a high pollution impact, also acoustic; in some very intense agricultural applications the machines are not able to perform good enough to optimize their productivity at the best. You can improve this a lot having better performances and productivity, without even open the ECU!
You can have a stronger boost at low revs, faster hydraulic movements and a better loading capacity with less fuel consumption on a long term. Moreover, the lowering of the engine revs and of the noise improves a lot the quality of your daily work.
