I'm trying to figure out what I'm doing wrong. I just bought a tial 44mm wastegate. I put the springs in for 20psi and it hit 40psi. Went home and put in the springs for 10 psi and still hit 40. I'm not using a boost control hooked up from turbo to side Port on the 44.
Do I have this hooked up wrong?

It's hooked up wrong. The boost source needs to be to one of the lower air ports. The top 2 are for when you use an MBC or EBC.
