Don't worry guys, this isn't a wind up by some spotty 13 year old school kid. ;)
I'm the wrong side of 40

and have a decent paying job as well as a few other 'interests' which funds things like this (along with my racecar build -

Apexi make a fully programmable ECU which is specific to the ST205. Simply unplug the OE unit and plug in the Apexi one. Base maps included so drive to the dyno to get it set up.
The stock injectors may well be able to cope with the power I end up with, but there is the risk that they'll be getting close to their maximum flow. I don't like running things close to their capacity - always have a built in safety margin IMHO - hence the bigger injectors.
I'll keep you all updated with pics as it happens
