boost problems

Hi All ,

I recently bought classic impreza turbo with de cat and remapped to 254bhp
Its an x members car , merv or something from gorey
When i start her up in the morning engine managment light comes on (was told this is due to de cat) and runs rough on boost
After few miles it goes off and runs a little better .
I dont know if it has been mapped for higher octane fuel ( maybe some1 here might know )
or its a sensor or something ?

Any help would be great

Thanks,
Alan
