I just installed the Injen Intake and Intercooler pipes with a greddy Type S bov. I recirculated like the stock one. My concern is that when I get on it in between shifts it feels like the rpm's get stock at a certain rpm which makes the car jerk, but when I drive it slow the car is fine. Can it be that the BOV is too lose or too tight?

Any imput will be appreciated
thanks
