Brabus
The BRABUS PowerXtra Kit will provide you with a relatively decent HP increase:
Base E 350 CDI
+ 35 kW / 48 HP to 230 kW / 313 HP + 70 Nm to 690 Nm
The great about this unit is that MB will still validate your warranty and this unit itself comes with a 4yr/48,000 mile warranty from BRABUS.
No other ECU upgrades offers these types of amenities.
Thank you
