I just installed my profec b and am having a bitch of a time adjusting it.
One thing I noticed is that the lower the gear, often times the boost will rise beyond what I set it at causing fuel cut. When I shift, my boost spikes at 5 psi over what I set it at as well. I'm a little confused on this, as I know the bov is supposed to release that pressure, and i can hear it doing it, but still that seems a little wierd doesn't it? I would think fuel cut wouldn't jump around so much, same with my boost....

my mods are
hardpipes, hks ssqv bov, profec b, bic ddp, greddy sp, kn intake...

I would suspect a wastegate or solenoid problem. You have the ssqv hooked directly to the manifold not the TB right?

where are you checkin for variances in the pressure for the bov? judging from your previous post you have it recirculated, i think? theres a little nipple on the back of the bov, wheres that hosde run to?
