Hi
With much help from Vortech, John Cooper Honda and Tuning Japanese the car is running well and getting 12.2:1 air:fuel at high rpm. It is also pulling well at low revs and at the start of the boost curve which was a previous problem. I am running a Mugen Pressure plate, Helix disc and a Mugen sump as well as all the Mugen cooling bits. The pictures tell the story:

The engine bay (note position of FMU)

We are running the 12:1 FMU set-up rather than the 10:1 to get extra fuel which is needed at higher rpm. I am also using an APEX-i VAFC for fuel tuning only. This is running on Shell Optimax and special NGK Racing plugs on a cooler rating with recessed tips. These will need changing every 3-6,000 miles. It runs very well in this setting and keeps cool - also its great fun. Any people in UK or Europe who are looking at the Vortech kit then please join in this post with questions - I'll do my best to answer them.
I'm no car buff, what does that mean in plain english, what does it do to performance, whats the risks, does it de-value the car and whats it cost you to do?
Personally i dont see the point of modifying an already brilliant motorcar
