The RJC boost controller. Questions I have.

[Ttype6]

Using a helper spring to raise boost will still have the wastegate cracking while spooling.

I'll assume this is a response to what I've written. I don't see where anyone is saying that a heavier wastegate spring does the same thing as a manual or electronic boost controller. You can only get so much boost with a manual boost controller. Eventually you'll need more wastegate spring to get more. The wastegate spring and boost controller do two different things and work together in a coordinated effort to accomplish a desired goal.
