This is true on this car since it's MAP based, the DME will detect the change in pressure when the valve vents and adjust fueling accordingly. But I still stand by my statement that the setup should stay the way it has been tested and designed. Reducing variables in a mix usually leads to more positive results. On a MAF based car it would cause all sorts of issues. EAS makes a good point about the venting on deceleration out of boost. It could get quite annoying, but since you're 6MT try and see if you like it. Personally I'm not a fan of non-intercooled setups, so I'd opt for the 600 kit.
