Noobish question, but will an auto-equipped car blow off pressure the same as one with a manual? I was thinking about it, and if you're on the accelerator, the throttle plate is still open when the auto shifts, unlike when you let off to hit the clutch and shift in a manual. So, does it release pressure when it shifts? Or does the whole intake stay pressurized because there's (theoretically) little to no change in boost pressure?
