is optimised, since that’s one of the key reasons to replace the factory valve (as well as longevity
and boost-holding).

As the tech article explains, the turbo will make a different sound under certain conditions at low
RPM (only noticeable with an aftermarket intake), which is not compressor surge and is not harm-
ful to the turbo or engine, but nonetheless some people may not like it. In that case, removing
the spring will make the DV+ behave like the factory valve, so the different noise will be gone.

The boost pressure and turbo are fairly irrelevant as far as the main spring go. You could poten-
tially say as a blanket rule to the guys with a DSG gearbox that they can install the DV+ without
the spring, because throttle response on gearshift is much less important than it is to the manual
guys.
