1996 12v not building boost
 

Hey guys, I have a 12v in an 01 f350 dually I just finished swapping and much to my dismay it won’t build more than 10 psi of boost. It has a ground fuel plate boost elbow(disconnected for diagnosing) AFC and plate full forward. Fuel screw flush with nut and star wheel half way stock injectors stock turbo with a wicked wheel and new exhaust wheel due to the lefty tighty mishap. It smokes a bit when building the 10psi but not too bad. I have build a pressure tester and through the turbo intake it’ll hold 25psi until it blasts the tool off. I found a couple leaks and fixed all until it started holding pressure and blasting the tool off. I’m at a loss at this point and any help would be greatly appreciated. Thanks.
