Finally booked my in for the FPM375 and 1st Service, hope it makes a reasonable difference, have read plenty of feedback, some say it’s great others say it doesn’t make that much difference on the later RS, mines a 03/2018 so guess it’s classed as a later build, I love the car to bits, first RS drive and i was hooked, said i would never go down the performance route again but couldn’t help myself, my only very very slight niggle, in std form it does lack the mid range punch. Fingers crossed i’ll be smiling come March.
