'89 T16S boost problem

Basically when cold it boosts fine, but once warmed up I get the APC solenoid chattering and boost cut back. Car still flys in 2nd (high yellow/red border), but higher gears I get barely more than base boost...foot to the floor in 4th and it's constant solenoid chatter...I've fitted new plugs (ngk 7ev) and dizzy cap but no change...

I'm thinking as everthing works as it should when cold it must be mixture or HT related, rather than faulty APC system?

Disconnect solenoid valve and It's nice and smooth with boost exactly half into the yellow....
