Why spend money when you don't have to? A new or rebuilt wastegate should function perfectly. Boost creep is generally an issue with worn springs. A boost controller is a redundant system, it allows the boost pressure to be seen by the wastegate after it hits a preset number/amount - the same thing a functioning wastegate does all by itself. The usefulness of a boost controller is adjustability. If you don't want or need adjustability you likely don't need a boost controller.
To me it's just another gadget that can fail or get you into trouble. Ever heard the term "dial-of-death"?
Wrong......wastegates have a spring to prevent exhaust leaks.....when not on boost or low boost .....that's it. Their time in automotive engine management as a primary boost control has been passe for twenty years..
A wastegate spring will be fine for that purpose at 4.-.6 bar.
The boost controller is infinitely adjustable...will never leak...and can be managed both manaully or electronically...by the operator or the ECM.
