Sorted at last, after work last night I went down to Aungus in Galway, he tweeked the map a bit(hard reset the ecu, and reduced wastegate duty by 2%) and shes running perfect again 
I had tried the remove battery terminal for 30mins and drain charge to try reset but he said that doesn't work, you have to hard reset them via software..
