Cobra Intake problem

[sgwinn]

I just put on a new Cobra intake on my 90 essentially stock motor. Nothing else was added but the intake. Well, it runs pretty well, but there is a noticable bog when you first start out. Used to be i could nail it in first on a rolling start and it would have perfect acceleration. Now, it bogs and then takes off; but even when it takes off, it does not seem to have the same torque that it did before when it was fully stock. Is that because it needs a bigger throttle body to let more air in? Idle is perfect and runs great at constant highway speed. thanks
