I just installed an Autometer boost gauge in my WRX MY00. When the engine is off it sits at 0 as expected. When I start the engine it sits at around 24 VAC which seems lower than I'd expect. But the strangest thing is that at full boost in every gear it only goes to 7 PSI. So reaches same boost of 7 in every gear which obviously is very low. I have checked the line for leaks but can see anything obvious.
