Civic with vafc fuel setup

well, i've only dynoed my car with the bluebox at 5.5lbs of boost. and i was running really rich, it didn't go any leaner towards the end of the RPM band. WEll, i will still choose to stick with the bluebox unless it gives me problems like you're having with it. BUt i was saying that i was gonna use 270's i said 370's which is a big difference. Yes 370's will yield me really rich mixture at mid RPM range but a VAFC should cure that problem. Good luch at whatever you do, let us know what works for 10lbs boost, thanks
