Check your coil packs and clips for cracks. Sounds like spark breakdown to me.

I dont have a pressure drop from reading the boost gauge but its a drift bov, im thinking spark either coils or plugs just dont understand if it is would it miss or play up through the whole rev range?

Ok had a look replaced plugs, cant see any cracks on coils, but two plugs the plug into coil are busted, would the current going past jump across to each other???

Yep. Under high load the spark will jump. You can try and put electrical tape around each pin or buy a new set of clip of ebay for about $50 I think.

Bad idle, using extra fuel spark breakdown and a few other things. Open the ecu up and take a look. It should be obvious if they are leaking as you will see the damage or fluid on the board.

if the caps are stuffed would a Greddy emanage fix the problem or would i still have to fix the caps? also does the emanage get rid of boost cut/fuel cut and speed cut?

Yes it will get rid of all the cuts but you still need to get the caps done as emb is an interceptor ecu not a stand alone. So if the main ecu is playing up the emb will not run correctly.

Did the boost increase when you put the new mods on? I would assume that it did. If so, did you check the gaps on the plugs to make sure they were correct for the extra boost?

This would be one of the first things I would check, as you said it is only happening when boost is above 9psi.
