Hah!!!if u have a good luck in the tuning mags ive seen a device for it in there...i beleive its like a purge...it just fires a little fuel into the exhaust and the heat in there fires it up....bobbbbobbbbobbb!

Stick a resistor accross the intake temp sensor to make it think it's still cold. Use a switch near the dash too select when to enable it, and label the switch 'chav-mode'.
