Sounds like fuel cut.
Have you modified the car at all without a remap?

I've had the newage coilpack conversion done, could that be the cause of it

Too much turbo boost is the cause of it, the ECU is cutting the fuel when the boost pressure is too high.

You still running that switchable chipped ECU? If so what setting is it on?

Yes I am, its on the 1.1 bar, just seems to cut out for a quick second like it has a limiter on it

Yeah, you are hitting the fuel cut limiter, try it on the lower boost setting, if it doesn't do it on that then you need to lower the boost pressure on high boost to 1.0 bar.

You can do that by adjusting the waste gate actuator arm on the turbo.

I've just changed my switch over and it's boosting perfect now, I don't think I changed it back from when you were at mine that time, so I've been using the 0.6 boost instead of the 1.1  Embarassed Embarassed Embarassed 
Thanks for all the help  Very Happy
