today i bought picked up a used greddy profec b 2 boost controller, and i cant get any boost out of it, it came with the greddy boost solinide and another replacement, aem style one.
so installed it, i am getting -0.90 vacuum and only 7.9 psi of boost, that what the factory wastegate is set to.
i tried everything, i even also rewired for the aem style boost solenoid and it wont build past 7.9 psi
i tired following the instruction manual, ive played with every setting and nothing works… ?
anyone off some help
cheers
