What excactly does this relay do ?
Can it cause a low boost problem ?
I'm still only seeing 8 psi: I've already checked the actuator rod adjustment and its set correctly, i've bought a new w/g solenoid and i've installed an aftermarket boost guage to accurately monitor the boost levels and all to no good ! What in the heck can my problem be ???

Code what?
Did you install the new solenoid? Where did you tap in for your boost guage. Make sure you have the hose's on the solenoid correct.

I tapped into the upper intake (past the t/b), yes i installed the boost solenoid and yes the hoses are correct. (according to the info pic on this sight)

its not a relay it's a solinoid. it's mounted to the top of the turbo and regulates the amount of boost the WG actuator sees.

if you are only getting 8psi or base boost, it's not bleeding off anything ie not working. chek to make sure all fuses are working(even the ones on the back of the alternator then run DM or a scantool of some sort to see if the ECM is commanding it to work right. is this only on the first try? if so thats bc the ecm commands it that way on the first time it sees boost from start. the boost gauge does change how much boost your turbo makes. something is a miss did you hook up the lines coorectly?
