I was thinking along the lines of many EFR IWG setups having surging issues. I wasn't aware of the majority of EFR EWG setups having creeping issues. Better than surge!
I guess you can treat boost creep like a state of mind.
Not everyone builds boost maps to be level pressure across the entire RPM range.
1) If you are total power output limited, you can run more boost at lower/midrange RPMs and taper off to seemingly have a HUGE powerband.
2) You can build a slowly increasing, linear pressure line in which peak boost is at peak RPM.
Centrifugal Superchargers do this by design. It makes the car easier to drive when the powerband is linear in reference to RPM.
3) If you were to build a Highway Racer (bad idea?), you could set the car up to build almost zero boost all around town to be reliable, boring, and get great gas mileage, then drop a gear and load it up to ramp up pressure only when driven HARD.
It's all application based, driver preference.
