Another GLS400, also known as GL400, now with tuning by UPstage.
Today we did chip tuning for Mercedes GLS400 with a 3.0 liter petrol engine, M276 DE 30 AL, with a twin turbo air supply system.
Fuel injection is controlled by Bosch system, so the control unit is installed by this brand.
The firmware is read and written from this car through the OBD socket, there is no need to remove or open the unit.
As a result of chip tuning, we received 393hp and 587nm., which is +65hp and 112nm., which is very pleasant for this body type.
