As title I have a blitz k24 , zisco wastegate , aem tru boost controller since fitting them I can't get it to boost at what I want just keeps boosting to 1.7 bar I've tried changing the wastegate spring from a 1.0 bar spring to a 0.7 bar spring I've tried adjusting boost controller even right down to minimum but still boosts at the same 1.7 bar any one got any ideas? Help Much appreciated Cheers mark
