I don't think it can help to reduce turbo lag, as the turbo still requires the same rpm to generate the same boost as before, but I guess it would instead improve the spool up time as the 水喉掣 does help to keep the turbine spinning almost all the time. But we do lost all modulation from the factory standard EBV.
There is other type would be a Pressure Bleed Valve, provide that your factory EBV is still working properly, you can install the PBV along the pipe to the turbo actuator, and then set the PBV to raise the base boost from 0.5 bar to 0.6 bar, while retaining the control effect of the factory EBV.
Ok to bid for it at low low price, you never know you may get lucky! Don't know whether it comes with manual or not, it would be quite difficult to setup without the manual.
好似放血咁.
好想呀....
