1) Why can't I get my GT to boost over 14psi??

I have a Turbo XS HPBC manual boost controller, and no matter how much i turn it up i can't crack 14 psi!!! I have the MBC vauum source running from the throttle body, and the other end connected to the wastegate actuator, just as TXS instructed; so what gives???

2) Why does the AMX 1397's "burst of power" mod not work when the stock Diverter valve is disconnected??

I have a Turbo XS RFL-H BOV installed on my GT. When i am only running my bov, this mod does not allow me to spike up to around 20psi; it only works with the stock DV connected.

Thanks guys
