First long drive last night, really pleased with how she drives now, the flat spot has gone she seems to run cooler and much smoother.
Next job is to find out what size the thread is on the stock O2 sensors, so I can remove them, I'm going to fit a blanking plug to one and the other will be used for the new wide band O2 sensor that will come with the AR gauge.
AR gauge will be used for more precise tuning of the EJK controller.
