Is this normal, or is there something I can do to fix the problem.

It's just lifts with almost any throttle closure. Even just easing off the gas, I get some CBV flutter. Holds boost fine @ 21/22 psi. So that's not a problem. But even on the highway, after giving using the throttle, and easing off it it get some rough spots.

Anyway to fix this, or is it just the nature of the beast.

Currently running the next to stiffest spring with 2 preload washers. Should I remove those?

 

I have this problem too. Take a picture of the dv call mike at forge and tell him you are sending the pic and he will tell you if you have the old piston. Chances oare you have the old style.

 

Damn, just bought the thing new not real long ago. I could live with it if I have to. Any kind of "deal" he swings guys with an older style piston?

 

I am waiting for mine now, they are backordered and waiting hopefully late this week they will be in. I just bought mine about 2 months ago and it is what is left on shelves in shops. Forge is replacing them for nothing.

 

Sweet and thank you very much for the info.

 

no prob
