I'd be interested to see if flashing a map with reduced WGDC adder would prevent the overboost. I don't know what would cause overboost issues like this other than boost solenoids. Unless there's some kind of obstruction in the intake piping?
So one suggestion elsewhere is pinched vacuum lines which may cause slow release of the WG and contribute to overboost. I'd considered walnut blasting the intake but if it was crap on the intake it wouldn't explain why the issue popped up from nowhere after the injectors/overheat/waterpump episode. Pinched lines might if they're taking things apart and not putting things back together correctly.
