Greddy Type-S Boost Controller problem
 

Hey guys,
I've been having problems with the Greddy Type-S boost controller that was just installed in my car. Basically the boost will not go above 6-7 psi no matter how you adjust the knobs. The unit itself has power, and the solenoid was tested and works. All vacuum hoses were checked and there are no boost leaks either, so I really don't know what the problem is. The shop that installed it said that there may be something wrong with the unit itself, but I wanted to hear your guys' input before dismissing the unit. Any help would be greatly appreciated =)

check that youre getting power to the solenoid and make sure youre feeding pressure to the controller unit.
