For anyone interested in remapping their V40 D4 MY2015. Here is my before and after. No hardware mods so far. No changes to fuel consumption, getting around 60MPG+ if driving sensibly on motorway. It was remapped by an individual first, then taken to a dyno about a month later to check gains. Should have had it done whilst on dyno but I wasn't wasting another £200. Happy with what I got. Anyone else had similar gains? Don't want to overdo the components anyway.
