2014 s3 remap

Hi the clutch on my 2014 s3 was slipping under load, I?ve just remapped it stage 1 and now the clutch is slipping on hard accelerating as the remap has transformed her into a beast, but I?ve been advised I may need to upgrade the clutch from a standard one but am struggling to find one, has anyone done a stage 1 Eca remap increasing by 40/50 bhp? If so did u have to upgrade ur standard clutch? Did it start slipping??? Cheers
