well it was running an amal valve but that died, (blew apart then electrics failed)and it never made the boost with that fitted
so i put a t piece in the actuator pipe to see if i can get it to make/hold boost and it still doesnt even with the t piece jetted down to 2mm on the actuator and compressor side and a 5mm bleed to atmos
and then i tried taking the boost hose to the actuator offf and blocking it, so it ran the actuator alone so in theory should make loads, and its still the same
which says to me, dodgy turbo, or a leak which i tested for and cant find.
