Hey guys i finally got my boost gauge installed today, among things i should be happy with this installed boost gauge. after the install i noticed that my car is running abnormal boost patterns. the car first runs to 10psi and then up till 4500rpm the boost drops down to 6-7psi and hesitating up and down between there and 10psi. i mean i should at least gain another lb of boost with the exhaust upgrades listed below. Instead the boost patterns seems to be weaker than stock. I know that this topic has been up before. but the problem was never really explained. Also what kind of vacuum am i suppose to be reading at idle and at running speed 60mph (cruise). I'm getting 16-18 of vacuum at idle and 21 at cruise speed. For those who fixed the problems please give me feed backs. Also how would you distinguish which and what is the problem of the weird patterns. Thanks a lot
