Purchased this M50 Manifold Fitting Kit from a guy called Eric
http://m50manifold.com/ I came across his kit after looking about on forums and he has lots of positive feed back and looks like an excellent kit. Just got to wait for it to be shipped from the US now
Also sent my ECU off to a company called EndTuning
http://www.endtuning.com/ who are deleting the EWS and raising the Rev Limit to 7k, Also adjusting it to work better with the M50 Manifold.
