Changing Boost in a FD
I want to change the boost in my 1993 FD with stock turbos. I have a AEM solenoid boost controller but PO did not have it hooked up. Looking at the diagram supplied by AEM I need to connect to the wastegate and somewhere to input boost. My question is do I need to use a tee and connect to the precontrol actuator also or just connect to the wastegate. Do I need to disconnect the the wastegate solenoid and the precontrol solenoid? Thanks

31) How do I turn up the boost?
Allowing the stock system to run above 11psi is not advisable without modifying the stock ECU, since it isn't programmed to respond to boost above 12psi. As well, the fuel system is limited to 13psi. Once those systems are upgraded, boost level can be controlled by installing an electronic boost controller, a manual boost control valve, or installing a pill with a smaller orifice. BOV settings do not affect working boost level. For smaller increases in boost, the PFC and other tunable ECUs allow adjustment of boost using the stock wastegate components, however at higher boost levels this is not advisable due to limitations of the stock wastegate solenoid and actuator.
