ahh yes, it could be spark blow out from too much compression or boost, nay need to up the spark

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???

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.

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

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
