I assume it was boosting more up until recently?
One thing I would do is check the BOV. Take it off and see if you can blow through it, if so it's broken. Next thing would be to check the EGCV connection to it's actuator. Do a search on here for EGCV there should be some info about it. If both of those check out try putting it into TTC mode and see if boost returns to what you had before.

Well you could choose a stock clutch, which wouldn't be a bad choice as it's very tried and proven, or you could go for one of the many stock based clutches with uprated pressure plates.
I went for a Centreforce dual friction, which is stock based, and have no issues to report with it. Mind you i've done less than a 1000 miles on it since fitting.

You'll be looking between £400 to £600 for a good clutch (just under £400 for a stock clutch). Don't forget you should also replace the flywheel when doing the clutch, which is around another £350, the flywheel bolts and thrust bearing. There are also some other miscellaneous C-clips and washers which are worth changing whilst you have everything apart.
I just had a quick look on Whifbitz and they seem to do Competition Clutches which i've honestly not heard much about (don't go for a paddle clutch). You could also try Chris Wilson as I know he used to supply an uprated stock clutch.
