I'm hopefully going to book the SVA soon and am aware that I need to do certain things to get the R1 engine to pass.

I know I will need a CAT and will probably rent one if it fits my system but what about fueling etc? I have used the std airbox will it pass on the std map?

Any advice experience gratefully received.

I've been lead to believe that the injected motor needs a power commander to get the emissions down for the SVA.

You have your problems in the UK and we got ours. In Sweden emission is not an issue. Here is the weight of the car the problem. 1,5kW/10kg is what we need...
