Does the Machinator array changes the size category on the character?

How does the benefits of the machinator array, the STR bonus, affects a good quality cybernetic limb? The limb has already a bonus, so, it is replaced or they are added together?

Thanks in advance.

Size is not mentioned, so it stays the same-the tripled weight being the tradeoff. As for cybernetic limbs-the strength and toughness bonuses all add together. The Machinator Array is explicitly an add-on to both biological and extant cybernetic parts, rather than replacing anything-that is in the description. Think of it as a bunch of extra pieces added to what you already have, like a bunch of pistons and servos bolted on to your limbs and a collection of plating and wiring all over. (basically the difference between someone with a couple of bionic limbs and a few augmetic implants compared to what most Techpriests look like in the art)

Thanks, my wife has both and she is going to give me headaches from now on.
