Cobb fmic and forge bpv problems..!

[SharkDiver]

Hey all,Ive had my forge bpv for awhile with no problems.Now I have the cobb fmic and I cant get the tension right on the bpv.What happens is when I let off the gas at around 2-3k rpms the car jerks from the bpv tension not set right.With my stock tmic I had it set with blue spring and 1 shim, now with the fmic Ive tried blue with 2 shims and 1 shim and no shims.Also I tried the yellow spring and still get the jerking.I dont know what else to do since the yellow is the weakest spring and it still does it but not as bad as with the others.So last night I just put the stock bpv back on and I have no problems.Is anyone else running with the forge bpv and cobb fmic having this problem?Im not sure what to do so I may just sell the bpv.

Ideas?

Thanks
