There are many potential causes of poor performance. I recommend getting a copy of the WIS and stepping through the troubleshooting chart under "power too low."

Any one of the below will negatively affect performance. Unless you step through methodically, you will just be guessing.

• MAP pressure sensor failure
• Charge air pressure sensor failure
• Atmosphere pressure sensor failure
• air leak in intake
• mass air flow sensor
• wastegate failure
• charge air control valve
• fuel pressure
• fuel flow rate
• injector flow rate
• evap purge valve
• DIC
• spark plugs
• poor fuel
