Is this your stock boost gauge, or is it aftermarket. The stock one is usally off by alot. Also check your vaccuum lines, not just the intercooler pipes. It could even be the hose going to your boost gauge or boost sender. There are plenty of places for air to leak out unfortunatly.

alright fellas.

If your engine knocks you don't even know it unless you have a mechanic's stethoscope or a screwdriver to your ear on the engine while it is pulling load. The car feeling sluggish is the only indication you have that your engine *may* be knocking.

If you are boosting and the car isn't going anywhere you may have a code 52 CEL. Check/replace knock sensor
