Well, thats freaky

Just got back from looking at it. I have been racking my brains thinking about it and decided it must be something faulty with the wastegate. Took the down pipe off, and there it was. The washer was sitting too high and catching on the housing causing it to sit open. So cut the top off the arm and re-welded it in a lower position which made the wastegate seal properly.

Over the moon. It was then missing under boost, so checked the plug gaps and they were set to standard 0.8 so adjusted them to 0.6 and problem solved.

One last thing to sort out, I have set the actuator to the standard setting. The car peak boosts to around 1.1-1.2 bar then settles back to 0.7-0.8bar. With the car being 'Stage 1', what should the boost settle at? I was thinking that I would need to adjust the wastegate to hold around 0.9-1.0 bar, does this sound about right for stage 1? or does it sound like the car is still running standard boost??

Nearly there,
