The FPM375 map can be purchased without the induction kit for £419 +vat from Ford.
The rest of the £1000 is labour and and parts that make up the kit.
So solely as a map, its pricing isn’t far off the mark.
And it’s a pretty good map, forget the top out figure of 375 it’s in the mid range you really feel it.
RS Edition.
FPM375 Rocks
The rest of the “M” maps suck
