You don't have to change PSI levels when it's that low. If you were talking like 8-10psi daily and 15psi at track, then I would be like cool....but 4psi and 7psi, not enough to warrant driving daily on. My girl drives daily on 8/9psi.

If the wastegate (spring) determines the amount of psi that will be used, then how do we determine with a boost controler the amount of psi we will use. Does the spring also has to be changed or do we leave the spring (7psi) and add the boost controller? Very confused about how to control it.
