Just installed my IC and I'm having a weird problem. Watching my boost gauge, I start the car and the gauge shows around ~10inHg, after a few seconds it will pull down to ~20inHg (normal). It will continue to do this until the car gets warm, take it for a drive and at stops and off the gas its pulling ~20inHg, on some occasions it will jump up to 10inHg while at a stop but rarely. This isn't a slow transition either its a jump in inHg like a switch is being flipped or something is cycling if that makes sense. Car idles fine, I've checked all the vacuum lines and replaced a bunch. I just can't figure out why it is jumping back and forth. I pulled the IC today and resealed just to make sure, but no difference. Anyone else seen this?
