Clutch Slip Again

Probably been covered b4 but can't find it in search !

Got a 2007 TD5 one of the last built. Have a JE ENgineering ECU upgrade and a Gwyn Lewis exhaust. Goes very well. Engine only done 36000. New clutch last Jan 11 as it had started to slip due to increased power / torque.

Done 6000 miles since new clutch (OEM) now starting to slip again. Light use with little towing but may increase this year.

Any suggestions on clutch upgrades to overcome this ?

Fit a 130 clutch kit

I'd look at why it's slipping. Shouldnt happen even with standard clutch, maybe rear oil seal or something.
