Hartge ECU tuning - Opinions need it

I have an F11 525dA, 4-cyl engine which produce 218hp / 450Nm from factory.
The Hartge ECU module claims to bump this up to 258hp / 530Nm.

The added power would bring this car to 530d level. Is this too much strain for a 2.0L 4-cyl engine? The car is new with 6000km on the clock.

How easy is to remove the module (and all the wires) if something goes wrong and I need to bring car for a service. Can it be done by myself? Open the hood and unplug it, or do you need to dissemble some of the motor parts?
