Stage 2 HDi clutch?

[Silverainbow]

Slam Wagon mentioned Berlingo clutch?, I take it that's the van variant and not reverse pull, what sort of power will these tolerate?, my clutch does need changing and I have no issues with doing the job but can't afford helix and don't want to be doing the job twice.
Am currently running std hdi90 engine with blanked egr, fmic and cat removed, going for stage 2 map next
Any input will be helpful
Cheers Guys !
