haha thats a crazy idea i might just hide one inside my glovebox to scare people in the passenger seat :twisted:
to be honest mate those adjustable boost valves arent really any good for the 5s due to the carb.obviously you have to set your carb up accurately to the amount of boost your running
therefore adjusting the boost would mean having to change the amount of fuel going into the carb which means changing jets.as the carb obviously cant adjust itsself as an efi system would be adjusted by the ecu it would just cause your car to run an incorrect mixture probably causing more damage than having that little extra boost is worth :wink:
