Thanks kur4o
I'm pretty sure it was the injectors struggling at a low pw below 1mS
Car ran fine around 13.5 afr then trim the ve table 1 cell & we were up around 15's afr.
Idle was OK. It was when the rpm rose and map fell the pw fell below 1mS.

I've swapped the injectors back. These are idling around 1.6mS so we're off playing again.


Thanks
