hmm, was just thinking, i cant get like 100% throttle as it cuts like theres not enough fuel,
but..
it's making 10psi boost and maybe trying to make more, so it's possible that it's trying to make more boost but there is not enough fuel/pressure to do so and therefore it is cutting
does this sound likely?, i think it could be my problem, which means i need to create a leak, probably just wont seal the lid on the carby box for now

more air will only make it worse, you need more fuel otherwise it could lean ut too much and melt pistons or rings.... more air = more go... sounds like not enough fuel

I take it that you ignition is up to the Task, if you wind the fuel pressure up and it is still the same. I'd suspect coil.

problem is my pump is only rated to 14psi, so i cant get more pressure, although my gauge reads 16psi when i run it, im not sure if the pump is underratted or my gauge in-accurate
why the coil? as in it needs to be upgraded or isnt working properly???

there is no way a standard 1200 coil could handle the load of a turbo, you'll need at 25- 30KV for decent burning, thats the equivalent of a spark jumping about an inch gap, to run that you'll need modified points or eletronic ignition

could reduce spark gap for temporary measure till more spark found

just get a nissan one off an efi engine, you can buy kits from dick smiths to upgrade your points. plug gap 1.1mm BPR6EY-11
edit: use the above plug after new ignition, otherwise set currnet plug to 0.5mm and dont run 100% throttle
