If all the kjet equipment works, then its just as tuneable as digi for peak power, if not more. As said, mine makes 159.5, higher than the quoted 150 from the mk3. If the kjet works fine and is set up spot on, its hardly worth buying the digi loom + parts, then swapping it all in, for a 'tamer' engine. Digis can be a nightmare for faults/ fault finding also
