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
