I've looked on James's website at the MJ base map which shows 27 degrees advance on idle, this is based on a standard metro turbo dizzy, however i remember reading that you should never run more than 20 degrees advance at idle, is this figure correct and if so is it because it compensates for the vacuum advance being disconected?

15 degrees seems to be an ideal max figure, if you still need to raise the idle with that, add more air.

anything more tends to cause problems with emissions

So when some joey comes on here about how his 16v turbo vauxhall is great compared to ours, he can be given the 'bird'...

Yes, this is very true. To get my 998 with a 276 cam through the emissions I had to retard the ignition massively. Drove like crap, but gave the engine time to burn all the fuel and get through emissions. It always failed on unburnt hydrocarbons.
