I've just installed a front mount inter-cooler, I need some help on the boost pressure. When it was installed it was only making 5 psi and it was running at 11.5 psi before the mod, I've temperally stuck a bleed valve on it it's running at 9 psi but I noticed it was cutting out at 15 psi is this normal on a 93 wrx.
Ok also, what I need to know is do I have to move or change the actuator? and also I would like to run the boost at 16.5 psi. How can I get this boost before the ecu cuts it off and being safe?
