Chiptuning is basically a software optimization on the consumption scale. In the case of a professional adaptation of the engine control, the durability and service life of the engine and drive are roughly equivalent to the standard values, provided that the additional power is used to a small extent, because any higher load will inevitably lead to higher wear Noticeable increases in performance.
Among other things, this is due to the fact that the limits of the performance are not gas-dynamic (knocking) as in the case of the Ottomotor, but, above all, mechanical. In other words, almost every turbodiesel motor can significantly increase the power at the expense of its service life.
