Ok folks,
Swapped out the GGR board for a nice new one from Ahmed tonight and guess what?
The missfire seems to have gone Super happy at the moment as this has been pushing me to the point of getting rid of the car altogether
Couple of little things to sort out now. Its only boosting up to around 14psi and dropping to around 10 so i think i need to wind up that actuator a bit
Also the boost control Valve (ammal valve) is clicking really fast and loudly so im guessing its knackered
Hopefully once thats done i can get some fun out of it at last

Ok,
After a long discussion with Ahmed it looks like i might be getting somewhere.
The P8 Management will pulse the boost control valve really quickly if there is a problem with a sensor or the likes. This avoids running the car with full boost and damaging the engine. It's also a way of telling you that something is not working and needs looked at.
After running through everything i've done to try and sort this it looks like it could be the Lambda Sensor thats giving greif and causing the low boost. I will get this changed out and update my findings

New Lambda fitted thanks to Ad (adamski frst) so early signs are good.
Put an extra turn on the Actuator so its boosting to around 19/20psi.
I will run it like this for a while just to be sure everything is ok.
Also the clicking from the boost control valve has stopped so it looks like the P8 was doing its job and telling me something.
One thing though, the GGR board must run without using the Boost control valve because it never clicked with that fitted
