Forge DV Bucking
I seem to get "bucking" when ~3800 rpm ~ 10 - 13 psi part throttle conditions (e.g. going up a hill and just wanting to maintain speed). This is happening with the Blue spring and one shim installed - should I use a softer spring or a firmer spring ?
What is causing the bucking ? - is the DV not releasing air back into the intake (i.e. too stiff a spring) or is the DV releasing air back into the intake (i.e. starving the engine of air and thus too soft a spring) ?
I have read numerous threads on flutter, but none that explained why the bucking was occuring or how to resolve.
My setup is a stock 9 turbo with peak boost ~29 tapering to ~22 at redline.

Thanks for the feedback, but it is the DV....If I put the stock one on there is no problem....I spoke to Patrick @ Forge today and he acknowledged the issue and provided the standard try softer and try firmer springs....
