Just bought a 200 civic dx, with a fully built motor and a wrx turbo. Ill give you more info on request if you need it to help me with my problem....... The car runs perfect and the boost works wonders when it hits boost. Only thing is when in low rpms the car bogs a little bit but as the rpms climb, the car will start to stop bogging. But if I hit boost it doesn't bog at all... any ideas what causes the bogging in low rpms??
