I recently installed a new GFB Hybrid WRX BOV and have encountered a few problems. Somehow I knew I would have fluttering issues at low boost levels, but what I didn't expect is boost spikes. So far, I've seen it in 2nd-4th gears. At WOT, after max boost is reached(14psi), my boost gauge jumps to about 17psi for a split second then comes back down to a normal range. Does anyone know why this happens? Does anyone know how to fix it?? Any help would be great!
