Haha Nick you nutter!
Another product I've been looking at today is the 'GMC Free Powr Unit'.. Basically it attaches to your throttle position sensor, and then you put your toe down it engages and stops your alternator from charging the battery. So instead of an engine mod which creates more output from your lump, it merely free's up power that is alreadying being produced.
The mechanics sounds spot on, and for 140 of my money, and 3-12bhp gains at the wheels, it sounds pretty good!
This GMC version is available for BOTH Cit and Pug.. Oi oi Nick!
