100% not turbo related. I'm thinking the map is so aggressive that its over fuelling the car.
This has only happened after the remap just over a month ago. It's also intermittent, it does not happen all the time.
I am taking the car back to Evolve next week for the map to be put back to standard. I'd lay money on it that when its back to standard, these symptoms disappear.
Thanks for the input chaps...
