I've also got a spoon chipped ECU.
It's only when the engine is really hot and only does it at high revs from 3rd to 4th. I can make it do it too just rev tits off it and put it into 4th and she flames nice and good. It's not every gear like my last one.
I don't see it as a problem everything seems good. I've just been to Southend and back today to give the car a good run out and it was perfect.
