i have a autometer boost gauge and it only reads 4-5 psi max dont understand it brand new 57 trimCT turbo and wastegate from PT. With shims i only could reach 6psi. When the car is at idle whats the vac supposed to be. I think im going to try boost controller this week if that doesnt work im going to purchase the HPF IC kit and see if that helps cause maybe i have a leak somewhere. It has to be small cause i just inspected all those connections. And where is the best place to plug in gauge vac line right into the throttle body right.
