dose a 2007 gxp have a boost controller

There is no external or adjustable controller. Boost levels are set within the programming of the ECU. You can put a screw type 'bleedoff' external controller but I would not reccomend it. Get a custom tune or the GMPP performance tune, the stock ecu leaves up to 50 HP on the table. HTH
