Well if it wasn't doing it without the power box and it's doing it straight after it was fitted I'd be looking at the sensors in that area first. Might even find that when the car's under load the power box is suffering from this weak wall problem that people have been having causing an air leak. That's obviously just a thought but I'd check/ get the powerbox checked over before changing anything else.
