I have a problem with my MY95 5dr.
I've changed the dawes device for a scoobyecu and the boost will run to 15psi for about 5-10minutes of a journey, then drops to 6-7psi until I stop the engine and start again. Any ideas whats going on?

I've tried cleaning the boost solynoid(sp) with brake cleaner, I've tried and failed to find the black and green wires for the ecu code check.

Thanks.

 

Symptoms sound like the ECU is switching to safe mode, ie running dropping the boost to 0.5 bar.... i don't know enough to give suggestions why it would do this, sensor failing maybe, perhaps speak to whoever did the ECU for you.
