I know the last post on this topic was a while ago but I have a MKV with the AMD re-map and a panel filter fitted.
Before the car was 201.8 HP and 220 lb/ft of torque and after it was 260.8 HP and 291.4 lb/ft. The car is running on Optimax also.
I agree the figures may be a but optimistic and will only know when I put the car on another RR but the difference was massive, smooth power but aggressive, it totally transformed the car I could not believe the difference.
The only criticism is a slight dip in power/flat spot? at 3000-3500 rpm when accelerating hard through the gears from 3rd upwards. 1st and 2nd are awesome now compared to standard.
