Stop driving the car mate!! Flashing CEL is the knock sensor telling you there's knock occurring in the engine. Get rid of the boost controller and put the Subaru control system back in place until you get sorted. Ticking noise? From the engine? It might already be too late for your crank.

Ah, I think the power fc can be configured to flash the CEL as a shift light. Maybe get it off to a mapper who knows what they're doing to get it all checked. Not worth losing an engine over!

Hi yes I'm sure its set to flash for 3 things knock being one of them
Symptoms are overboost feeling when it happens but like i say clicking from solenoid when just powered up is very strange cheers

Could it be as simple as a boost leak that occurs on heavy load?
