the old fuel rail only boxes did and have had issues
most new types like my one the bluespark pro boost have boost monitoring
to stop over fueling and fouling the dpf etc so they have improved a lot
but saying that it is not recommended to have max torque and power settings
as you need to accept the fact that will not be good for the gearbox over time
but if you set it up correctly and stay within safe settings good improvements can be had
