SLK R172 200 Tuning Box

Has anyone on here fitted a tuning Box on a petrol SLK R172 200 or 250, if so what are your thoughts and comments, is a tuning box safe or not?.

I have one on my car and it certainly appears much quicker, it is a Bluespark box with stated gain from 181 BHP to 211 BHP and it feels like it.
The box links to two sensors, the Map sensor and the Boost sensor, can this box damage your engine, probably not, because it appears modern direct fuel injection turbo engines have very sensitive knock sensors and closed loop wide band Lambda sensors to protect the engine and controll emissions if the car strays outside of the manufactures limits set within the mapping and the many tables the EMU accesses. If a sensor fails or the fueling goes outside of these set parameters the EMU will throw a CEL and probably put car in limp mode. Early cars without these protection systems probably were damaged as it appears an uncontrollable lean mixture on petrol fuelled cars can destroy the engine in seconds.
