An intercooler is a must with any uprated map as the std one would struggle trying to keep the temps down when the turbo is pulling more boost.
As said, get yourself over to
www.focusstoc.com as the advice there is top notch IMO.
Cheers, I will check out that site.

Are they a necessity?

That sounds good to me. Should see a big difference with 275 from standard. I'm not going to worry about 10 or 20bhp here or there. I'll see what happens. Before I do anything I'll drive it hard standard and see how it feels. I don't know what sort of power an ST is capable of through the front wheels while still being a nice car to drive. Ideally I would like an RS, but I couldn't justify spending that sort of money on a car... and then I'd end up wanting 400bhp.
