From a technical perspective, the ECU is typically a Bosch EDC17 (likely), and the transmission is many variants use zf 8-speed automatic (where fitted); manuals also exist..
Considerations: High tuned torque: check transmission torque capacity and service history.. Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.
Fuel economy note: economy gains unlikely at full power; depends on driving style.
