Saw this on Niki's Facebook, huge area under the curve, bet you're happy. Totally transofrms the car doesn't it, you soon realise how dull and flat the car was, especially at lower rpms.
Clutch will start to slip at some point as its probably never been replaced if manual. Personally at that stage of tune i'd stick a standard one back in it. I'm still on a standard clutch at the moment, replaced it last year, and its handled the last 6k of hard miles at Stage 2+
