I don't understand how it can be mod specific when there are so many different exhausts and intake mods available all I'm sure with different flow rates, so you'll still end up with a pretty generic map. However, if you happen to live somewhere too far from an uprev dealer, then maybe this is an option, but, with most of the country within 100 or so mines of one, then I still recommend paying he extra £25 + fuel for the uprev.
