Yeah, and you have different springs inside the wastegate because if you are only running 7psi, you don't want a spring in there that's opens up the wastegate at 25psi.

Basically, you have different PSI springs in the wastegate to give you a baseline of the amount of boost you will run. If you will run no less then 7PSI, get a 7PSI spring. LIke if you will run 12PSI on the street and 20PSI on the track, you have a 12PSI spring in the wastegate, then set the boost controller to 20PSI for the track.

You just can't do the reverse.
