Are you still using the factory injectors???? I remember u asking about injectors.... If so id say that is your problem. My injectors wouldnt flow much more than that. With the malpassi reg, ca18 inject, and good fuel pumps i was able to run 22psi+ easy. As for the ignition i ran a S2 dizzy - which i think your running??? Have you fitted a boost retard unit and sorted it all in that regard?? If so then run some BPR7ES plugs (or 6ES's) gap them down to around 0.6mm and youll be right!!!!!!!!!!!!!!! Then boost up 10psi is ordinary you want to at least double that....

I would be checking the fuel pressure while this is happening. If your regulator is not responding to the boost quickly enough then it could be lean. But that would be after I checked the plug gaps.

Subject: Re: still funny under boost....cuts out intermittently.hi, as it approaches max boost (10 psi max) , you will be accelerating,
then it would cut out for a tick, then accelerate again, then it would ,
maybe sorta run a LITTLE funny for a bit , then accelerate again, .
most of the time this happens in the period of about 2-3 seconds, then some
times it might happen fractionally., then once in a while it will be okay.
i will check into those plugs.mark k
