Mercedes GLS-Class (X167) GLS400 d 4MATIC Chiptuning

For the Mercedes GLS400 d, a lot of extra power could be extracted. A proud 65 hp and 137 NM performance increase with the PowerBox from CPA. Thanks to the individually developed software, which is specially adapted to the GLS400 d, safe chip tuning can be realized. The additional power suits the Mercedes GLS X167 very well. The PedalBox also works excellently and the different optimization levels can be selected simply at the touch of a button.
