just crush the stock ix bov. I am also running e85 at 28psi and it works great with very minimal flutter. (I'm coming from a vta hks lol) stock bov is the best but if you want to run high boost then there will be some trade off with flutter and aftermarket bovs. I think a properly crushed stock is the best way to go.

I don't really have any flutter problems with the Synapse at 26 psi. I really like it... so much so that when someone accidentally smashed my last one I just ordered another one right away.

sounds like a vacume or port issue. i know they can be finicky for some people..Aaron at ER has an idea for my car using vacume from the fuel systum to where if i lose fuel pressure it will automaticly dump boost.

Balancing your spring rate slightly on the light side can effectively use the bov to vent the surge or no? For instance my hta71 part throttle surged or fluttered bad witv a rfl bov with washers to stiffer the rate. Soften the spring a lot and driving was way better .. although sacrificing something.
Thoughts?
