so i just swapped my s14 sr20 and i already set the boost controller to 15psi (ecu was tuned for 15 so im leaving it that way) it makes boost but right when it makes 15 it drops all the way to 9-10 psi (around 5-5500 rpms it drops in every single gear) it has vacum (-16/-17) i have a AEM tru boost controller. im sure iv set everything right on it but idk im stumped.. PLEASE HELP!
