Better low rev response

Can the original be adjusted (e.g. preload) to produce better response and achieve full boost??

Not sure on the figures but i assume with a pressure gauge to avoid any spiking or creeping it could benefit?

I'm sure it comes preset from Protoxide to improve what you say it will improve. The point of a aftermarket wastegate is to keep boost at high RPM, thus the spring iside is stiffer, therefore not opening the wastegate as much at a desired boost setting as the stock spring would have been preset.

I'd not mind trying this.
