Mitsubishi Colt czt

Hi people I drive a colt czt. he has 150 ps series and I would like to make an increase in performance to approx. 190-200ps. I would let that be done in a professional tuning workshop. they have in common that I can drive 200ps without any technical changes on any case, so without motor or gearbox to change something. this company would make the increase in performance via a mapping, so by optimizing the software. I apparently need to improve the performance the Japanese motors can apparently tolerate a lot when it comes to something like that. however, the durability of my motor is also very important to me, or I don’t want to wear it out too quickly or overload it. I know, if you change what the performance is, of course, the veil is also higher but I prefer to be more careful and rather ask in the round. someone here knows about these motors and can tell me what to watch out for should? is basically advised not to do that or does it really not if I stay in the ps frame? thank you for your reply
