Easy just requires fuel rail plate and a afpr
and most AFPR's that folks get are the FSE's
deffo change the lambda sensor in the manifold, also check or change the water temp sensor, both will make it overfuel and fail the emissions. adjustable FPR would be a good further step too.
thanks nitousvaux its cheap enough to change the lamba and water temp sensor so will give it a try....will let you all know what it comes back with thanks
