Don't know if thats necessarily a good thing but part throttle feels a little crisper.
Full throttle = no difference from stock DV's.
Throttle modulation is the gain with Forge DVs over stockers. Stiffer springs more play on throttle before boost is bled from CP.
That is what I have understood in regards to aftermarket DVs vs Stock and use of different springs.
And that holding pressure in CP is not damaging the turbos , that happens only if ongoing for long periods. And when you let your foot off the throttle in most cases pressure in CP is bled out thru DVs. If I understand this correct.
