I disabled mine because the engine slows down between shifts faster.
Other than that I see no difference in boost lag or popping on decel, but some people do get more popping in the exhaust with it removed or disabled.

It's an annoying vacuum limiter being called a deceleration valve when installed in an '87 930.
It's purpose is to lower hydrocarbon emissions on deceleration, and it has no effect on boost lag between shifts on my car.
