Well, I have a profec b spec II and a turbosmart 45mm wastegate on a single turbo. When the boost controller is on I cant hit more than 7psi, sometimes it spikes to 13psi. The boost controller is set gain at 14psi , 35% set, 30% gain. What gets me is when I turned off the boost controller and did a wot at 3rd I hit 1.57 on the pfc commander, I shifted to 4th and the same.My inj.duty was at 81.9 when that happened. I have the nc side going to the upper intake mani, and the com side to the wastegate. I search and cannot find a answer, any help would be appreciated.
