CP-E Tial QR spring
 

Okay I'm a little lost on this topic, I'll admit. But should I be running a slightly weaker spring than my idle vacuum or should I be using a spring that's matching my idle vacuum.

According to my AP when the car is warmed up I'm idling at -10.4 psi or something which is like -21 inHg. When I'm driving either I'm driving like a granny, or the spring seems like it's closing shut too fast. (Boost gauge seems to be reading the same).

Forgive my rice needs here, the valve sounds good, but it really seems to be closing too fast. If that's the case what spring should I get to compensate for that? I feel like it shouldn't abruptly close like that on part throttle spool.
