Not wanting to hijack the thread but my car will be running a similar spec/power and after reading a few comments about turning down the mixture to pass the m.o.t . Surely if the car is set up right in the first place it shouldn't be a problem?
Finding a place that can set them up here, let alone charging a mint for it, I don't fancy some muppet screwing up the mixture every time it needs an m.o.t
