When on the road you can generate boost spike or longer sustained higher boost in 4th/5th that can cause fuel cut or boost oscillation, dependant on where the boost/fuel cut threshold is set.

Could be worth looking at the tune to see what it's actually mapped to achieve vs what it's achieving and where the limits are set.
Thanks for the right up a advice mate. You could be right. It was road mapped by fb tuning a 5 months ago and done it once on the drive home, but it has done it since then until the other day. He had mentioned the the actuator needs adjusting but it already had been. He advised a new turbo housing and is on my near future plans. I will pull the plugs tomorrow and check the gapping. Hopefully all should be good soon
