danny - how do you know what spec that chip was designed for and if yours is the same spec. You will need to adjust your fueling and boost too for the chip and a few other things. I would get it checked by a PRO IMO.
I have recently changed my ECU from a L1 on greens to a L6 on blues but then the engine came with it
and there is no warning light coming on mine - so it could be you have a duff ecu or something. Personally get Stu to come round if it aint too far from him and you cant get it out the garage
im sure he will have it running in no time
oh and rudey your sig is fookin funny
