I would stick to what it was mapped with. A lot of difference between yours and a non turbo car.
They are not that much more money and hardly worth saving 30 quid and having the car have to hold back (or worse) cos they aint up to it.

Mapper changed them as said it allow him to squeeze the last bit of umpf from the car. Imo od either swap them to what in there now or bite bullet and put iridums in. End of day no matter what they are a better plug and eont cause you any lose of power only gain if any. It could be pleecbo but iirc i did get a better mpg

I just use copper NGK 7s, under a tenner a set. Copper conducts better than iridium too
