I hope you're letting your car warm up before boosting or you'll blow your motor in due time...

there is a waring printed on your visor.

Let it warm up completely and then see what happens. The fuel maps change quite a bit once it's warmed up.

Your temp gauge will should be at the halfway mark, thats optimum running temperature. Usually it'll get warmed up after 5-7 minutes of normal driving. Once its warmed up punch it and watch the boost gauge and see how it runs. When was the last time you did a tune-up (ie. plugs, wires, fuel filter, o2 sensor, oil change, etc.)?

You should replace all those wearable parts every 40-50k miles except for the oil of course! Do that every 3-5k mile depending on how you drive.
