It is 276 BHP (280 PS) standard on 100-102 RON fuel.
An honest 350 BHP on any dyno on any day on plain Optimax or SUL will need a change of turbo, fuel pump, full 3" exhaust.
A dubious 350 BHP only on some rolling roads could be done on the original turbo.
If it is a twin scroll turbo then it might be a bit easier - see Bob Rawle's project thread.
